Doesn't sound like you are going to be doing anyting to fancy with it, so not much too worry about when it comes to "extra" money for programs.
I have a Mac. I have no problems with it or compatibility. My HP printer works fine. My wireless non mac keyboard works fine. My wireless non mac mouse works fine. My Western Digital external hard drive works fine. Bootcamp that comes with all of the new mac computers fixes all the rest of the Windows "issues".
I got one for Dan's dad. He is 70 and kept getting viruses on his PC because he and his friends look at porn (tee hee) and other questionable sites. So, I got him the Mac and not a virus or any other problems since. He loves it and thinks it was well worth the money. He had very little learning problems when it came to the switch from PC to Mac and he is 70.
You also get face to face, awesome customer service with the Mac. I had mine replaced with a brand new one 6 months out of warranty. It had to be fixed 4 times, but I had spilled a vodka and cranberry on it. Go figure. It was all my fault and they replaced it.
You can get one refurbished here:

They carry the same 2 year warranty that the new ones carry and they are usually upgraded, too. You just have to hawk the website because once they put them up they put them up in groups and the good ones go fast because the price is so low. So just check it every day a couple times a day when you are ready.
