I like very much the resistive screen of the n900.

It's the only phone I know with a useful browser, because you can tap on very little details and links.

And you can use the pressure sensitive myPaint.

The capacitive "stylus" I know are very bad and not precise and not pressure sensitive.

I don't need multi touch, if the OS is provided for single touch.

A digital compass would be nice.

I like very much the excellent work of Nokia on Maemo.
