(Small things, but...)
Today I had to took my car to the garage, so had to tell my manager I'd likely be late (public transport is not terrible in our area, but it still takes me about twice the time to get to the office than it would with the car). I'm also down with a laryngitis and I can barely whisper.
I could have booted my home laptop to send an email or IM, but meanwhile the bus would have come and gone. So I hit the road anyway, and thought I would somehow email from the phone.
But then, the Nokia N900 is no Blackberry; it's a full-fledged linux desktop in your pockets. When I enabled the 3G data connection, the button nearby was the one to set your IM status(es) to Online; so I fired that up, looked up my manager in the wonderfully integrated address book, and she was online, so while I sit on the bus, we had a friendly chat about things to do, without having to share them with other commuters or strain my poor throat.
All the while, I was listening to the latest Python 411 podcast about the (apparently terrific and currently-slashdotted) Sikuli project, updating expenses on the little program I've developed (which I'll upload to the Ovi Store in a few weeks, I promise), and browsing Google Reader. The 30-mins commute was over in what seemed like seconds, and the experience was basically the same I could have had while sitting at my desk with a regular laptop.
This little thing is simply outstanding. Apple's new "iWhatever" better have a SIM slot, or they can kiss goodbye to their iPhone marketshare.
