Snow Leopard has been released for this season..
You system must be a New One.
Forget about Snow Leopard if you have a 4 years old PC running. Mac cant entertain rusty Desktops.
Snow Leopard does not supports Old PCs. This sentence makes no big trouble to Apple.
Microsoft Windows Se7en does supports Older PCs, even the one built in 2001 - This Sentence makes a big mess.
The Word Upgrading to new Mac OsX becomes Conditional. Installing windows se7en is just a piece of Cake.
Apple authorities earlier said that , Snow leopard is going to concentrate on performance, but they failed to reveal the fact that "Running Snow Leopard needs a PC with good performance".
Microsoft proves themselves better this season.
