I've got one with the same specs, it's cute, but definitely not a powerhouse. Can't even play youtube smoothly for the most part.
Yeah I got a spare iBook G4 I hardly ever use anymore roughly same specs I guess, YouTube is painfully slow on it as is flash, but I guess thats no surprise to anyone as Adobe are pants at everything they do; exc. PDF lol. Also I avoid HD video all the time as the computer just hangs.
