I see the N9/Harmattan as a step back from the N900 UI. I'd prefer a swipe in Harmattan take you straight to the task switcher, and have the 4 quick launch icons docked to the bottom of the switcher, with a task launcher/app drawer in the middle.

Harmattan eschewed widgets, which I see taking alot of usefullness from the device. How easy is it to check weather, individuals' online status, proc speed, or other "at a glance" info from our N900s on an N9?

I see the Notifications/Activity homescreen is a glorified widget, but a good one. Maybe we could design a fullscreen widget that accepts FB, Twitter, IM, and SMS notifications that, when selected, open the accompanying app.
