I'm listening to Tunewiki with lyrics, having just received and read a push email, Nim IM online and Sportstracker GPS running in the background, I have just taken a picture and attached it in an mms, whilst browsing and posting to this.thread. And all this on my Nokia 5800. I could start up a video but it would pause if I looked at one of the other open applications.

I'm not knocking the N900, I love.mine, but I've been multi-tasking for ages.
