I got an O2 Joggler at a throwaway price. The device looks great, and packs a good enough power from inside.
o2 Joggler Specification:
Screen: 7 inch Touchscreen
Resolution: 800 x 480 pixels
Memory: 1 Gig onboard, expandable via USB.
Power: Mains only.
Video formats: MPEG-2, MPEG-4 part 2, MPEG-4 part 10 (H.264), WMV 9, DivX, Vc1, FLV
Audio formats: MP3, WAV, WMA
Size: 180 x 130 x 115mm.
Weight: 700 grams
The device has a USB connectivity, and is entirely hacker's treat. Runs Linux 2.6.24-19 kernel. I already made the device do thousands of things that the seller never intended to do thanks to google. Looking for experimenting with the Software platform, which is interestingly Flash based. Every App is a flash. (quite a story, compared to iPad). The touch screen is great but still lacks the punch of Apple.
The only bad part : no batteries, runs on Mains. Need to do something about it.
