Heck yeah. I play flash-based games like dark orbit and also poker (game.com). NO problems with locking up or slowing down, just sometimes it's hard to see the whole game on the screen, due to limited screen resolution settings. So, yes you can play games on the netbooks like the msi u100...but you need a bigger and faster laptop if you're planning gaming on a daily basis on your netbook. One thing I did notice is the netbook I have doesn't play videos well, maybe due to the fact it has only 1 gig of ram? So for very high res games or videos, make sure the laptop/netbook has a premium graphics chip and a lot of ram (like 2+ gigs).
