Bun-

I got a galaxy s (vibrant) on tmo. Yours is a much better deal if you have coverage and don't have to roam. Haven't touched my n900 in a couple months.

Try astrid tasks. Syncs with google tasks, widget for home screen, fairly customizable. Works great for things that don't need to be on a calendar.

As a non-programmer, not much I miss from maemo, and far more things that work well on android. One thing I do miss is the fm transmitter occasionally. Recently picked up a motorola t505, bluetooth hands free, with fm transmitter. Works nearly as well a as the n900, and will transmit voice calls through the radio, then resume music.

*oh yea, enjoy your new toy.
