I owned the 7710. When I subsequently bought the 770, my first IT, I couldn't believe the family resemblance between the two. Series 90 for the 7710 was a very clean full touch (including stylus) interface.

Of course, shortly after releasing the phone, Nokia announced the 7710 was the first and last of the Series 90. They've been doing this "kill it before it has a chance to be successful" thing for a while.

The 770, the N800, the N900 (all of which I've owned) seemed to be worked on by "off in a corner" teams - without the full backing of the company.

The N9 is worse. The company seems to have gone out of its way to prevent success.

A company of great people (well, once it was) with great ideas (all those concept phones) some great products and surprisingly inept management.
