Actually I'm the "close application after you're finished" type of guy, even on my desktop. But I find myself using multitasking on the N900 even more than on my desktop PC. One reason is that compared to a full-blown PC with DSL-connection, my N900 on a more or less reliable 3G/2G-connection is relatively slow. So whenever I start doing something that I know will take a few moments, I use the time doing something else... Of course there's other situations when I do "real" multitasking, like when I copy part of a web page, send it by mail, then read on... (did that just a few hours ago)... Or that other occasion when I had a chat going on and looked up the café the other person was at on Ovi Maps (satellite image was useful), then getting the time table and directions from the fahrplan application. That was a nice example, btw, as it really didn't interrupt the chat experience at all and I could just say "Oh, sure, I know where that is. It's right at Augarten park, isn't it? Could be there in 35min or so."
