Akihabara News reports today of a new mystery convertible Tablet PC-like device, the SA1F00A from Japan-based Kohjinsha. They haven’t uncovered much yet in the way of details but they have some photos of the device that are very interesting. Judging from those photos this mystery device looks to be around the same size as the Fujitsu P1610, maybe even a little smaller. It will be interesting to see if this is a full Tablet PC running the Tablet Edition or if it’s a touch-screen Windows XP only device. We’ll share more details as they unfold.
