What an interesting topic! Made me think a lot, but wound up depending on those of you with better imaginations than mine. For music: electric blues and Vanessa-Mae. But since a solar-powered laptop (thanks, MaryRinWI) is also on my list, I could listen to Pandora.com. If you're not familiar with it, go there! You pick your favorite tune or music style or musician, and they play that type of music. (And thanks to ipquilter for mentioning Nickleback, I wasn't familiar with the name, although I have heard it on the radio. I'm going to investigate further.)
And since I could get Kindle on my laptop (thanks for that idea, Lissette), I could read about anything I feel like at the moment. It would probably be mysteries and quilt books.
Thank goodness I didn't have to choose anything more specific about my music, books or the luxury item; I am so spoiled by my computer -- I can have it all!! Oh, and some Kaffe Fassett fabric
