As technology coordinator for my school this is a question I get a lot. Here's my suggestions....(for what its worth)
You need to know what her college uses...if they are equipped and using MAC go mac..If they are using PC go PC. I have had classes where I actually brought up my laptop and installed the programs we needed or used during the course, but this can only be done if you are using the same format. (Also it makees it easier to e-mail stuff to the the professor if they are on the same system) Brand is not necessarily important, I have had HP's, gateways, dells, and macs. What you want is a computer that will run the programs you need.
Also, What is the main use? typing? research? If this is the case, you want to be able to surf fast and have several things open at once, but storage is not a big deal. Go for more RAM, less hard drive space. (I have one of the new dual core processors on my home computer and I love it) If her classes are going to require new and specific programs (like engineering or accounting) She needs to know minimum requirements to make these work well and not be slow and frustrating.
A wireless, internal network card is a must! Bluetooth is nice, but you can actually buy USB bloothtooth devices later if she needs it.
Don't worry about typing programs, preloaded programs etc. You can buy MS Office on E-bay later and pick just the programs you need.
Be sure it is capable of being upgraded to the new OS that is coming out soon (I can't remember what is right now)
Also...Pentium is not a requirement. The celeron processors are just as good for the general user. If she's not editing music or videos....the general user rarely notices the differences between a celeron and a pentium. The higher the processor speed the better.
Don't worry about an A drive, they're obsolete. A cd burner is fine and a DVD burner is just more money and rarely used. I would include a DVD player if you like to watch movies on the laptop, but I haven't found any other use for it. As a teacher, I often show movies through the LCD projector and run them on my laptop. but again, its all about how you are planning to use it.
I always recommend that you sit down and list how and what the computer will be used for and then buy what you need but always get the most RAM you can!
Don't be sucked in by all the glitzy peripherals they "throw in" these are not necessarly deals.
Sorry this is so long, I know ther is something else and if I remember I'll post it. If I can help let me know.
