I always use multitasking, when I'm browsing the web, especially on this forum, when I'm messing around on my N900 file manager, mc/xterm open and 2-3 web pages for reference. I love multitasking and after 1.3 + swappolube and a bit of OC is working nicely. More memory and processing power would be handy with extended battery life of course.... or at least a solar powered charger
