Personally, I think she would like a Mac because she loves her iPod and iPad. However, the extra cost is one concern. Also, I'm not sure about transferring all her funky old Works files.
Greenville is about 150 miles away. Charleston is only about 26 miles away but it's downtown--that is a nightmare drive that most people outside of Charleston try to avoid (myself included
). Downtown Charleston shops are for tourists, south-of-Broad aristocrats, and College of Charleston students. That is, people within walking distance. 
I appreciate the suggestion, though.
