I love designs like the Wibrain M1. There was an Averatec UMPC concept some years ago that had a similar touchscreen slider design, and I have a thing for the the Sidekick Slide and AT&T Quickfire. Its so....useful - you get all the benefits of a keyboard and a large screen in a smaller footprint device. Sure, it might be thicker, but that usually makes the device easier to hold. Mark me down as a fan.
So naturally, when news hits that the Wibrain M1 has been greenlighted for production, I'm pretty excited. To refresh your memory, the M1 has a 4.8" 1024x600 touchscreen, Atom Z530 processor, 1GB of memory, 16GB SSD, WiFi/Bluetooth/HSDPA, what appears to be a touchpad on the right side, probably a webcam, and the sliding keyboard. While the membrane keyboard might not be the easiest keyboard to use, it is probably better than a touch-based keyboard, so I'll take what I can get (the only one I've used thats any good thus far is Apple's; touch keyboards are really easy to screw up). The M1 will run either Linux or XP, as showin in the photo above. I'd expect it to come in at between $599 and 699, provided it is priced similar to the upcoming Wibrain i1 UMPC. The price is on the higher side, but still significantly lower than the (admittedly more upscale) OQO 02+. For a truly pocketable mobile device, I'd say it is worth it.
