Remember, it is just in how you view things... If I take that MBP, and day one install Windows 7, isn't it just another PC?
I know there are plenty of Mac people here that don't approve of that, but I don't want OS-X. It holds nothing I want to have. But I DO want a nice machine. Is it really THAT bad?
Nothing wrong with getting a MBP and only using Windows 7 on it. Computers are just tools...find the best one that fits your requirements and use it how you see fit. If some Mac "purists" don't like it, who cares?
One thing that I will note is that if you are going to do that by way of using BootCamp, then I do not believe you can completely remove the Mac OS. I believe that using BootCamp to run Windows on a Mac would still require you to have a small partition with the Mac OS on it...but I could be wrong. If that is the case, then the only "downside" is that you would be wasting some disk space for a Mac OS partition that you would likely never use.
I suppose if I must leave it there... I might at least find time to try it out from time to time... it can never hurt to learn something new.
