2 years E90 user here. Certain things I miss absolutely are the keyboard along with the D-pad (I used putty an awful lot with the E90), as well as the form factor where you could tilt and hold it in certain positions. Also miss the fact it was bombproof, but I do not miss the exterior screen (far too small), the lack of support for the internal screen from the various S60 apps, and horrendously slow pace of it. It also frustrated me how difficult it was to develop for.

Oh - and I also miss Gravity, but I think Tweego and Witter are coming on leaps and bounds.

For web browsing, Opera really came good with their latest release, but I can't look back with MicroB.

Favourite facilities so far: fcron, mypaint (great for note taking, sketching whatever), knots2, erminig, rdesktop and the fact that most (linux) tools I use daily are just quick install away.

The N900 is breathtaking piece of kit.
