Thanks, folks. We just got back from buying the computer. The biggest decision was whether to get the notebook or IMac. He ended up going with the desktop b/c of the bigger screen and more memory. We were in line -- it's taxfree weekend in North Carolina -- in front of a graphic artist who said she would not want to do her work on a notebook. DS says he felt a bit out of place b/c all the other students were getting notebooks, though.
We got the free Ipod AND a free HP printer/scanner/copier. Of course, I had to pay for them, but I'll get rebates. We also got $100 off for the "education discount" and saved about $100 by not paying sales tax.
DS's college actually has a contract with Apple and with Gateway. If you get either of those two computers, the college tech office is "authorized service." The college also supplies Microsoft Office to all students, so we didn't have to buy that.
We did get the extended warranty. I always wonder whether that is a good idea, so I'm glad to hear that it is.
