Bye bye BIG MAN, i used to like u, and still do.
Its true Windows is on around 90% of computers, but unfortunalety they did that the wrong way, simply by being evil (which is a M$ slogan from a long time). My opnion in Bill and M$ is, great that u did all that, but y should u be evil? Google is a dominant now in internet (lot of people think the internet is Google!!) and their slogan is "Don't be evil", its even hard to find someone who hates Google.
M$ after Bill will be very bad, and very evil, Steve Ballmer is never like Bill, like what we saw with Yahoo! few months, the guy wanted to buy the company from the shareholders, when Yahoo! rejected!!. Come on man, y should u be that evil.
Honestly, its time for Apple to rise, the air is clear, and the Apple products (iPod, iPhone, and Apple TV) are making lot of people think "if thats their phone, how the hell would be the laptop".
I will be honest and thank the man, not for OS's, but for lot of other things, like Office package, Exchange server, and others.
Good luck in your life, and charity work. My advice: "check on M$ from time to time, because Ballmer will ruin the company down soon".
