As the title says, I think having a widget for your email inbox (at least unread emails, but this could be a setting) in a Blackberry-like fashion would be very helpful.

Allow SMS to be answered from any desktop PC or laptop

Problem: You're at your desktop PC, the N900 is in the next room. You hear a text message (SMS) coming in. In order to answer it, you have to get up and fetch the device. Even if the N900 is in your pocket, you need to change keyboards and type an answer on the small N900 when a full-sized desktop keyboard is right in front of you.
This shouldn't be necessary. There should be a mechanism to make ingoing text messages pop up on any of your computers and let you answer them right away, without ever touching the N900.
