Fragile disc? + performance
Huh? What you talking about? Nothing wrong with the NC10 disc. Sure it's a disc and not an SSD, but unless you're going to be playing Frisbee with the thing it's perfectly fine.
Piro - Have you actually tried an Atom based PC?
Sure they're not gaming rigs, but hell, my NC10 is running Windows XP whilst playing 720p HD material, streamed over WiFi and upscaled to my 1080p telly perfectly smooth all with software codecs!! (and actually it does play many older games quite nicely). Hardly underpowered in performance terms for the job it's designed for, but it is low powered in wattage terms. This is why Atom processors are in my opinion going to be ideal for low powered, quiet HD HTPCs.
Sure £300 to £400 can get you a decent spec PC (as long as Apple's name isn't on it). Fine, in a netbook this size? Hmm, thought not.
Anyway, if your experience of Netbooks are those crappy "cut down linux" based budget EeePcs, then try these higher spec machines running XP, Win7 or even Ubuntu.
Depends on you expectations though. If you want top spec gaming rig in a netbook size device that's not a 300W heater and won't burn through the desk, then you're in for a disappointment. For everyone else who wants a highly portable, low powered, device for web, email, the odd document, taking to meetings, and watch a few vids on a flight, etc, these are ideal.
