Wise move to continue with S60 on Symbian for touch screen phones
Contrary to the above commentator, I think it's the wisest move by Nokia to base the new touch screen phones (5800, N97 etc) on the S60. This will make it familiar to the largest phone user community in the world. It's far better than, for the sake of 'innovation', come up with something different.
I would think it's far more a concern for Nokia to be compatible with its large user base, than being worried about binary compatibility, which is really a non-issue.
Some other factual errors of the above commentator should also be pointed out. Symbian was designed for touch-screen from the outset, it's not something bolted on. The first Symbian device ever, back in 1996, was a touch screen device and the very first Symbian phone, the Ericsson R380, was a touch screen device.
I would also argue that far more innovations have been first launched on a Symbian phone than any other OS in the market.
