Hey guys, thanks for the great responses. I'll answer the questions here.
Stu, she is a Psych major. Lot's of research and paper writing, so a tablet is off the table. If I had the budget I'd get a 15" MBP and be done.
Sunburn, she is going back to school after raising two kids - she's actually in college with my youngest. The eyes aren't what they once were. So 14 is probably the lowest I could go in screen size.
Brain, the T420s is on my list. 4 lbs with a 128GB SSD for about $800.
Zap, thanks I hadn't considered a Vostro. Costco had an incredible deal on a Inspiron 15R, but is sold out and have said they aren't getting any more.
Rookie, thanks. The Sony's were on my list, but when I checked Amazon they were all out of my price range.
Biostud, I'm on the fence about HP. They are what I buy professionally, and I'm currently running an HP desktop for personal use. I just think HP has missed the ball on the quality front. At least it seamed the Dells didn't have as many issues.
Thanks again, and keep 'em coming guys!
