There ain't no way it can replace a netbook!

In real terms, the CPU is like pentium I or II class, so it may just be able to manage windows 98.

Consider what apps you had with windows 98 and that should put it into perspective. You want a video editing suite on a 600Mhz PC? You could just about run Quake 2/3 and office without win 98 falling over.

Get some perspective! You can do ALOT more with the N900 BUT it will never replace a netbook, it's just too slow for that (and even netbooks are slow!)
