I bought a 13 inch MBP in August. It was one of the best purchases I ever made. My kids are constantly wanting to use my laptop vs. theirs (my old handed down Windows laptops). I would definitely get a MBP versus the MB or Air- for me, the backlit keyboard is incredible. Also, the battery life is amazing- I consistently get 8-10 hours out of a charge. I've worked solely from laptops for about the past 5-6 years; I greatly prefer the flexibility of the laptops over the desktops.
If you can wait to buy between May-August, you get a credit towards any iPod of about $229. You have to pay for the iPod when you buy the computer, but then get the money refunded. It was a smooth process for me.
Education discount on the MBP's is $100-200 depending on the model purchased. In most cases, if you're a parent, student, or educator, you can qualify for the education pricing with very little questions asked. This holds true for both the hardware and software in my experience.
You can run Windows on a Mac if needed for software, but I have yet to really want or need to do so. For the programs I use, I've found that the software is typically a bit cheaper for the Mac version than the Windows version. There's a good book called Switching to the Mac by David Pogue that you may find helpful- I believe it's under $20 at
Amazon.
