I dipped my toe into water of MacWorld 8 months ago and I'm perfectly happy with my decision. So, sitting at my white MacBook with wireless Mighty Mouse.... Things I like:

- Apple wouldn't lower themselves to providing hardware that isn't up to their software (so yes, it can be expensive)
- As a result, the whole experience tends to be very slick compared to the bargain basement laptops I would have gone for in the past
- It really does "just work" but underlying flexibility, if you need it, isn't always well exposed
- Only one piece of software has ever insisted on starting itself up at startup on my MacBook, and that was by Microsoft (and I just add to edit my user to stop it happening)
- It boots up in the same time as it did the day I bought it
- I like the Me service (mail/calender/online storage and so on, nicely integrated with OSX
- When I have lots of windows open, the dock in conjunction with spaces makes life easy.

Now.... The Mac vs PC question? I think Microsoft have a right to be a little aggrieved. Windows XP is a perfectly usable and stable piece of software. Little wrong with it IMO, other than perhaps it does slow down a great deal over time as you add applications (so, it's higher maintenance).

I wasn't impressed with Vista but I understand that Windows 7 does a lot to catch up with OSX (complete with a dock type thing). Also, with a PC, you *can* buy bargain basement hardware and get pretty good use from it (just be prepared for delays if you run more than a couple of applications).

A huge advantage for the PC (for me at least) is still my experience with the platform..... Need to set up a secure web server with web applications accessing a MySQL database? I can do that for no cost other than my time. It's the sort of thing I've just not yet looked into with my MacBook (Work? I have to use a cr@ppy Dell laptop for work).
