I like my mac and it does everything I would want of it. You pay a premium for a notebook of any flavour though. A desktop machine is much more upgradeable and much cheaper to buy.
I personally would not buy a "pc" mac at the moment. By the time they are able to run the Adobe software natively, there will be second generation machines around.
This is one of those times where I am sure I don't want to look at upgrading for at least twelve months until it settles down. Those times don't come up very often and it's a nice feeling that I won't be tempted for the immediate future.
A personal computer is just that, personal. Just because I use one, certainly doesn't mean that you will like it. I have always used macs and that is probably why I like them. The PC guys will have the same experience.
If you have any bought software already, that can make the difference. Other than that, buy a modern, well specced machine and you will be just fine.
