I switched from PeeCee's to a mac 11 years ago......never looked back.
That being said, PTurner is indeed right in that Windows 7 is the best windows yet, (Thanks to Apple

) and if you have programs important to you sticking with them might be your best option. A windows computer is cheap purchase so for many it is the way to go.
I personally do not want to use parallels or ever run windoze on my mac. I do not want to open my macs to problems, etc.
I currently have a 13" macbook pro. I just gave away my 11 year old 17" G4 imac....it is STILL working great. Can any 11 year old PC's say the same?
I like the smaller screen. I actually miss my 12" Powerbook. I drool over the small macbookAir.
I will need to buy another Mac soon for my wife.....debating over a new imac or just get her a ipad. Maybe I'll buy both.
I'm as fugal as they come, but my macs are worth every penny.
