Ars Technica speculates on what the Kindle 2.0 might provide:
… the general hardware configuration appears to be here for a while. The fact that they’re still selling the current version also suggests that they have committed to this design in all its white-plastic glory. In the long term, there’s still the option of moving some of the awkwardly-placed controls and of improving the E Ink screen (color and improved contrast or faster response times, seem inevitable) … All of this leaves changes to the software as the most likely candidates for 2.0 improvements. Realistically, we could only infer what Amazon considered to an acceptable interface based on what was released as 1.0. If this doesn’t reflect what they “wanted to release in the first place,” then all bets on what may change are off.
