I have 9 assorted computers running various unixes in my house and a virtual private root server somewhere in Dallas. I'd estimate that I can achieve 80% of every computer related activity I perform with my N900 in my hands, as long as I have network connectivity.

It also mean that I don't need to carry my ipod or a gps, although I'm not entirely converted to the device convergence concept yet, as an ipod is easier to carry around than a mains charger.

Heck, its still easier to carry a phone, an N800 and an ipod around than a mains charger. So battery life is the biggest single turn off for me, and I'm not saying the N900 is particularly bad - I don't think it is, but a revolution in battery tech is what we really need. Oh, and USB ports that fall out. Damn them.
