I love it when people release FUD as fact when they have never even tried it for themselves, and then cover their asses by some inane comment like "or that's what I heard anyway." How is it coded poorly? What exactly is it about it that is poor and makes it not work on a Netbook? $100 says you couldn't have answered that question in detail when you made those comments.
Anyway, I've played Minecraft on every system I could get access to and it works great, and without issue.
Well it punked my kernal, pwnd my hard drive, used up all my download, ordered a ton of stuff on eBay on my credit card, shot my dog, ran over my cat and deleted my WoW account!
So there! Nuh!!
