My advise: Go with Apple.
I made the switch from PC to mac just under a year ago, and I will never, ever buy another PC. The mac framework is much more secure than any PC, even with the best anti-virus software. My first mac was the 14" iBook. I loved that. It got great battery life (about 5 hours), and was relitively fast as far as laptops are concerned, though the powerbooks (and new macbook pro) do run faster than the ibook. The new opperating system also has a cool feature called "Dashboard" which is customizabe to your needs...you install small programs called widgets which are all free. For example, I have a sudoku widget, hotel finder, wikipedia, and of course a WDW trip countdown! There are litterally thousands of these programs.
In February I was convinced enough with the Mac that I bought the new iMac desktop, which is absolutely wonderful. It even has a remote to listen to music/watch movies/look at pictures from across the room. When I got the desktop I gave my mom the laptop, and she was able to adjust to the Mac system within I would say a week? I've also convinced a few friends to buy Macs and they too have no regrets.
Also, a little trick if you are even going to look into a Mac...go to the store and ask if they have anything open box. I got my desktop for $799, ($500 LESS THAN RETAIL!!!!). The open box computers put though a rigerous test, and then Apple allows you to buy the SAME warranty for open box as new machines.
I hope that helps you and that you will seriously consider a Mac, they really are excellent machines.
