Retro, if you're going to have an opinion, at least base it in fact, not just some made up fairy tale figures. Last time I checked, just about every damn computer you buy includes Windows. So if you buy a new laptop, Windows and Linux cost the SAME.
And Apple charges $30 for their operating system because they ripped you off in the first place. Of course they can afford to sell it for that cheap when you're at cheapest buying a $1000 computer.
And no, you can't put OSX on any computer, that's a load of bull. Sorry.
I don't know about macbooks being overpriced dude - they have a 10 hour battery life, where as a 6 hour battery upgrade for my laptop would cost me about $200 alone.
You just gotta get the right laptop, a $600 ASUS will get that much battery life.
Try again.
