I actually prefer 9" over 10" anytime!!!
I prefer the smaller keyboard,the cheaper looks;it makes it look like the expensive toy I never had when I was a teenager!
Apart from being cheaper, they also are more mod-friendlier.
Any notebook that's cheap is more bought to be modded (like the OLPC).
Besides it's lighter, and smaller; easier to carry around, uses less battery (smaller fan, smaller screen).
Many say 10"is the smallest, best size.
For writers,yes.
For programmers, no, 9"is great too!
and for travelers, no.
The reason so few people choose to buy a mininotebook is because it doesn't have a good enough supportive chipset!
I hope Ion will change that!
BTW, what's the memory speed?
