WiBrain's M1 has seen a pretty rocky road to launch since it first arrived on the scene way back last summer, but it looks like the company is finally moving forward with it, and reportedly kicking the UMPC into production. Despite its extended stay in prototype form, however, there doesn't appear to be too many changes to the device, with it still packing a 4.8-inch 1,024 x 600 touchscreen, along with an Atom Z520 processor, up to 1GB of RAM, a max 16GB SSD, and all the connectivity options you'd expect, plus some (presumably optional) HSDPA. The one big change from the early prototype is the slide-out QWERTY keypad, which now opts for some membrane-style keys that could make an already difficult typing situation even tougher. No word on a price or expected release date just yet, but it seems likely that it'll remain a Korean exclusive, at least initially.
