Over the weekend, I installed Windows 7 RC, a free, preview version of Microsoft's forthcoming operating system, the successor to Windows Vista. The Mac versus PC debate has gotten so ridiculous that even normal, sane people who wouldn't care one way or another are now hurling insults and tsk-tsking at family members and co-workers who have either fallen into the fruity Mac OS camp or the stodgy Windows world. You have to pick one or the other,' you'd be pretty mad, right? If you went to your favorite pizza place and tried to order mushrooms and pepperoni and the waiter told you, 'I'm sorry but you can't order those two toppings together. My Windows 7 desktop is spare, but just give me a few weeks.
