"Microsoft has an interest in selling as many copies of Windows 7 regardless of what hardware they run on."
Case in point:
That's a Macbook Pro running Windows 7 behind Microsoft's CEO.
And why not? MS gets its revenue from the OS sale, not the PC sale. Apple is a hardware manufacturer, Microsoft mostly isn't.
Incidentally, I use Win 7 on a Mac all the time. I can boot into it natively, but if I run it in a VMWare virtual machine I can switch back and forth between the two OSes. Works great, but there's just no comparison.
All my Macs are pre-Intel currently. The oldest, I've had over ten years, and it's still a workhorse, still going strong. But, the handwriting is on the wall, and I'll have to get a new one soon.
I'm thinking MacBook Pro 17,” since it's my first generation Titanium PowerBook, that's got the most wear and tear. It tangled with a dog while on the arm of the sofa, recharging. The case is bent. Hardwood and laptop casings don't mix. This one faired pretty well all said and done, still works fine, but the charge is intermittent, since it hit the floor on that corner. I won't charge it unless I'm in the room.
