Hello! My friend's laptop recently died and she wants to get a new one. She has about $1500 she is willing to spend. She isn't so sure about buying a Mac, she mostly wants a computer for work doing some presentations to students, at home buying and listening to music from iTunes & Rhapsody (so maybe not a mac?), and photos galore. She also wants something light in weight because she will be taking it with her to work and etc. She is also considering buying an external drive for all her photos. Any recommendations? For $1500 I know she can get a good machine, but I figured I'd post here and hopefully those more informed could give me more info to give to her! Thanks so much!!
