I for one have no problems with paying for the upgrade. Look at the excitement it is causing! That alone is worth the $20.00 ROFL. It makes for good reading!!
$20 sure as hell beats $200+ from Windows. Plus, its as simple as downloading it from the App Store and installing it. So, besides it being ridiculously cheap, its also easier than Windows. I say, bring it on!
EDIT: plus, you don't need to buy it. Stick with Lion. Its decent.
Not to mention that OS X is more stable, reliant, safe...
Need I go on?
I mean come on... Windows 7 Pro is $449 where I live. That is a rip off.
$50 for fantastic operating systems that work?
I'll take option 2 for $50 Alex...
Thats also a limited time offer. At the end of January, it goes up to who knows what price. 10.8 is $19.99 and will be $19.99 whether you buy it on release day, or 6 months down the road.
