College students, would you please give me some ideas?

My almost 20 year old grandson is going crazy trying to think of an appropriate gift to give his girlfriend of 10 months for Christmas..they are both college students, going to seperate colleges, she has an ipod, digital camera, all the toys you might have from living in Silicon Valley..he has a Wii that is getting a good education going from one college to the other.. he has suggested {to me} good jewelry, but in the olden days when I was dating, clothes and jewelry were off limits until you were engaged..am I to old fashioned? Also I have $50.00 to spend on her, any ideas for me? Any help would be most appreciated..Thank you from both of us..
