Often, a shotgun is used at the beginning of a dash, but not so in the world of connected GPS devices, where Telenav launched its Shotgun portable navigation device days after Dash decided to exit the hardware business with its pioneering Dash Express.

Unlike Dash, Telenav was no newcomer to the guided navigation space, being a leading provider of turn-by-turn navigation services to cell phones. Its customers include Sprint and AT&T, and consumers can subscribe to the service directly through Telenav -- even if their carrier doesn't support it -- as long as their smartphone does. The product is free to download, but carriers charge a subscription fee for unlimited use, or offer it on a per-diem price. Because it is designed for an inherently wireless device, Telenav software includes features such as traffic notification, which is a premium feature in portable navigation devices.

In addition to physical advantages such as the large screen, the Shotgun has at least one important advantage over Telenav's cell phone services. Since its maps are local, the device continues to route even when you drive outside of cellular coverage areas. But there's at least one holdover from its cellular heritage that Telenav needs to shed on the Shotgun -- an unceasing, bright blue LED signaling wireless connectivity, which is hugely distracting to the driver, especially at night. Perhaps a bundled strip of black duct tape will do in the meantime.

If the Nikon D90's questionable 720p movie mode did nothing for you, or if you're a self-proclaimed Canon fanboy through and through, there's at least a sliver of a chance you bit on the EOS 50D. Now that you've had a solid month to flex that shutter finger and pore over the results, how are you liking things? Experiencing a huge dose of buyer's remorse? Absolutely elated with the low-light performance? Did you find enough extras to warrant the upgrade from a D40? We're just looking to hear how you really like / dislike Canon's latest mid-range DSLR, and more importantly, how you'd do things differently if given the keys to the company's R&D lab. Get to spoutin', won't you?

This week's episode of Ask Engadget takes things back into the living room -- or the bedroom, or wherever you have a TV -- and looks at the selection of HTPCs below the $3,000 range. And c'mon, who's not into getting a bargain this day and age?

"My query is related to a what is commonly referred to as a Home Media PC. Recently I have gone through the wringer searching online for an HTPC which has the possibility of being upgraded when the time comes. I need it to do all the usual PC things (but on a 46-inch HDTV) and would also like to play RTS games, edit music / video and not go broke in the process. Looking online, most pre-fab vendors are charging upwards of $4,000 to $6,000 for potent media PCs -- what are my options for getting one between $2,000 and $3,000 (or less)?"

We know, the bulk of you are just moments away from blurting out "DIY!one1!," and while that's obviously a perfectly reasonable response, feel free to share of pre-built machines that just might fit the bill here. Later, you can beam in a question of your own to ask at engadget dawt com, but only if you feel led. No pressure.

While low-cost laptops are all the rage right now, there's still a solid chunk of folks out there willing to pay a premium for potent ultraportables. The Voodoo Envy 133 is undeniably one of the sexier small machines we've seen of late, and the internals are rather impressive given the size of the enclosure. Still, this here rig costs a pretty penny, and we've all ideas those who splurged have a thing or two to say about it with nearly two months of usage under their belt. Has the Envy 133 lived up to your surely lofty expectations? Are there aspects there you wish were different? How could Voodoo go about tweaking things whenever it finally decides to actually launch another product at all its successor?

Last week's Switched On delved into Celio's REDFLY, an austere smartphone accessory designed for enterprise users who manage their digital lives on their smartphones. REDFLY has faced scrutiny from the geek elite who have noted that, for about the same price as a REDFLY, one can get an independently functioning netbook that does so much more. A similar argument has also been levied at Peek, a wireless e-mail appliance that delivers only a part of what most smartphones can do.

But the two products could hardly be more different. Whereas REDFLY is a smartphone companion, Peek is a smartphone alternative featuring a slim design and a commitment to simplicity that borders on obsession. For example, Peek, like many modern smartphones, will attempt to guess your mail server information by your e-mail address. But if your e-mail address stumps it, there is no way to enter a server name or IP address manually. This omission is intentional, according to Peek, which didn't want consumers to have to find out technical settings. Instead, customers are directed to contact the company's support line where a customer service representative will set up the account for them.

The approach is in lockstep with the device's target market -- busy and less technical consumers, particularly young mothers, who find themselves increasingly dependent on e-mail and don't want the complexity of a smartphone or the high cost of running one on a 3G network. Peek provides an alternative to a growing movement within the cellular industry to force minimal data plans on advanced phones. And for consumers who find carrier stores less than inviting, Peek is sold at Target, and it works.

With the world seemingly focusing all of its heated attention onto the world of teeny, tiny netbooks, Seamus is turning his eye elsewhere. Have a look at his very important inquiry below:

"I'm a college student who's not concerned with owning the next smallest thing in laptops. I don't have as much time for video games anymore, but wouldn't mind being able to play them on occasion. However, I love experimenting with bits of movie editing, Photoshop, and recording drum tracks. Is it too much to ask to be able to do these things, at least decently, on a laptop? Looking to spend under $2k if possible, and battery life isn't all that important."

We'd say it's very possible, the question is: which machine is best for the challenge? That's where you come in -- after giving your input, send in a question of your own at ask at engadget dawt com.

Microsoft's newest Zunes (along with the 3.0 software) have been out for well over a month now, which means you've had ample opportunity to really test one out and form some educated opinions. Now, it's time to open up and let loose. Are you still down with the design? Do you appreciate the extras that came with three point oh? What else could've been added to really spice things up? Do us a favor and tell the suits in Redmond what you would've done differently, and moreover, how things can be made better the next time it feels the itch to bust out a software update.

Oh sure, the unremitting release cycle of new digital photo frames is growing a bit tired, but that's not to say these things don't make for the perfect holiday gift. Oh, and after you've contributed to the cause here, drop your own question in at ask at engadget dawt com.

"I'm looking for the best digital photo frame out there to snag for the holidays. My requirements are pretty simple: good picture quality, WiFi, RSS / Flickr support without any fees. Any help?"

Short and sweet there, eh Adam? At any rate, we'll toss in some general screen size requirements (let's say 5-inches and up), and now, we'll let you to it. Light up the comments below!

If our overly fannish announcement post didn't give it away, we're pretty excited about the HP Mini 1000. It has little to do with the specs -- the drop in screen resolution from the 2133 is a little disappointing, plus we would've liked to at least see what one of these netbooks could do with a VIA Nano under the hood -- and everything to do with the fit and finish HP is bringing to this pricepoint ($399), in both hardware and software. Peep our impressions after the break.

Thanks to a special blessing from the folks in Redmond, we've had an opportunity to thoroughly give the rejiggered Xbox 360 Dash (AKA, the New Xbox Experience) a serious run through, and we've got the lowdown on the future of your gaming life. As you probably already know from the numerous posts we've done and generally available info (Microsoft has been pretty forthcoming with this stuff), the Xbox team has completely revamped the Dash experience, giving the system not only a visual overhaul, but trashing the underlying tech and rebuilding things from the ground up. The result is a beautiful, intuitive interface which loses almost nothing from previous versions while adding a considerable new feature set to the mix. Read on for our first impressions.

We first caught wind of a slightly revamped PSP months ago, and the long-awaited handheld -- complete with a new, fancier and in some cases more dreadful display -- finally hit US shelves this month. For those that picked one of these up and have spent some quality time digging into the latest firmware, how are you liking things? Particularly for those that upgraded, are you pleased with the new build? Are you being plagued with those mysterious screen problems features? Could you stand to see a few more things tweaked for the PSP-4000? We suspect there will be quite a few mixed messages flying in this one, so let's get those comments rolling.

The latest question to fly into our Ask Engadget mailbox (which is ask at engadget dawt com, for those unaware) concerns wireless routers. But not just any wireless router. We're talking wireless routers that offer up rock solid reliability day after day, transfer after transfer.

"What is the best wireless router in terms of reliability? I know that question has been covered before, but most people just answer with whatever router they own. I've had issues with routers. Gone through three Netgears and a Linksys that after a certain amount of time cease to hold a decent connection. I'm wondering if people know of a solid router that might be a little less mainstream."

Who better to ask about the underground WiFi router scene than Engadget readers, right? Help this poor fellow out -- one more dropped connection whilst racking up frags and he's going to have a catastrophic meltdown.
