But anyway, Hyperz you're obviously biased towards Linux so it isn't worth trying to justify that Windows is a good operating system.
Compiz fusion and "Aero" are equally as good depending on the features you want and the system you run it on. They both do the same kinds of things, just one is for windows and one for linux. Not exactly "competition".
Also, Windows 8 isn't a major version, it's a minor version created based on Windows 7. Hence why it'll look very similar and have most the things 7 has.
As for bloat Hyperz, if you did have a 100Ghz 32-core CPU, bloat wouldn't affect your system. So called "bloat" will always be opinion-based (meaning some say it is bloat, some don't) and it'll most likely never be too bloated for the future systems.
Just try to remember that windows is still the primary OS being used today and you only think the way you do because you like linux. If nobody ever told you about linux, you'd still be on windows and would have the opposite opinion.
