Man I might be able to help you out. My wife and I just bought a second laptop. I'm in school and she plans on returning to school next semester. I knew the two of us would be fighting over our laptop if that were the case.
A netbook is just a scaled down version of a laptop.
Originally, we bought a netbook we found at Best Buy for about $230. Thought it was a pretty good deal and I figured since all I need is internet for research and Huskerboard and some word processing for doing papers, a net book would be fine. The one we picked out had Windows 7 on it and had a 160g hard drive. not bad for such a little computer. It was pretty small so carrying it wouldn't be that big of a deal. It was fairly portable. The problem I found is the one we picked out had no CD-ROM on it. I have Microsoft Office 2007 that I'm able to buy thru work at a re-donk-ulous price so I wanted remove the trial crap they always install and install my stuff. No can do. A decent external CD-ROM was going to run us about $70. So now we're looking at $300. We had also bought a sleeve to put the netbook in that was another $20 because I didn't want it getting messed up in my book-bag. So total we were looking at spending $320. We bought my son a Toshiba laptop for $350 that would be perfect for me. Larger screen (easier to read), larger keyboard (netbook keyboards are uncomfortable because of their size), larger harddrive (250 compared to 160), had CD-ROM and came loaded with Windows 7. We promptly returned the netbook and bought another laptop for myself for $350. When we returned it, the lady at Best Buy said they've been getting a lot of returns on those things for the very same reasons I mentioned.
My opinion? Netbooks are handy, but their probably not as practical as a regular laptop. Right now you can probably get a good deal on laptops with the holiday season here. Save your money and find your daughter a good laptop.
