ASUS W5A
edit: here are some specs i was able to pull up from newegg. i really like this little laptop(though i'm an averatec fan at heart

)
if you want, let me know, ill try and look into some more that have the min screen res that you are looking for. also let us know if the screen size matters...as in 12in...14in...15in...etc. what would be a good size for her. i personally think this 12in should be no problem but then again some ppl cant see well and so on. oh and provide a little bit more info and what she wants to try and do with it. as in, what else, besides adobe will she be using the computer for because this might help find a cheaper computer with perhaps a slower processor or faster processor, depending on her needs. hope this helps!
