I installed 10.7.2 today because I was going to buy an iPhone 4S. So I had a couple of crashes already, no big deal I thought. Except this time my entire Mac froze and it couldn't boot anymore. I was scared cause I don't have Applecare anymore. Luckily I managed to get it booting again cause I know a few tricks. Back to Snow Leopard for the 3rd time. I had more hope for 10.7.2. It's still a worse OS than Windows 7.
