MapleStory and netbooks

I don't have a netbook, but my (old) laptop has similar stats to most netbooks (almost everything except the widescreen, lol), and it works perfectly fine. It's my only computer. I tend to start lagging after an hour, hour and a half of Zakum, but that's more due to an overheating issue, which is due to the laptop's age. You might have to turn down the graphics every now and then.

Your quickslot keys might be hard to press, but you should be fine otherwise.

EDIT: Make sure you keep it tuned up, because you won't have much room for error with viruses, disk fragmentation, spyware, etc.
