NVIDIA is showing that wacky Mini 1000 / Tegra mashup at CTIA, but Qualcomm's not far behind with its own creative ways to repurpose smartphone silicon into MID and netbook-class devices. Making an appearance at Qualcomm's booth was a prototype PurseBook from Taiwan's Wistron, which stuffs a Snapdragon chipset into a device looking (and weighing) a little bit like a VAIO P. That's where the similarities to the Sony box ends, though, because Qualcomm sees the PurseBook (and devices like it) hitting in the $299 to $499 range -- we'd like to see them even cheaper, truth be told -- and you won't be running Vista here. Instead, you've got a pretty slick Linux distro from ThunderSoft that'll edit Office docs, give you a desktop-class web experience, and connect with social networks, which are the three things most of us spend 90 percent of our PC face time doing anyhow. It's not going to replace your laptop by any stretch, but with a claimed 8 hours of battery life, we could totally see packing this thing as an ultra-lightweight alternative for day trips. Qualcomm expects the PurseBook and devices like it to ship in 2009 -- as does NVIDIA, so we're definitely lining up for a sweet battle royale here. Follow the break for video.
