Whatever! I just dont like integration of metro UI in Windows PC operating system. Its just not done. Sounds impractical to me. I dont know why but this new OS should only be for tablets.
And I hope they fix bugs this time. I'd assume that the new Windows 8 would not have blue screen of death issues.
I'm no expert but if you mean copied java as in, copied the syntex, then yes, that was the goal/idea from the start.
No BSODs are nice but all it takes, on any system is a hardware failure or a bad driver and that's just something MS can't really control on their side.
