i know there was a computer thread here once before but i cant find it. my computer has crashed, basically, and i need to get something new. should i try a mac or get another dell or what? i dont do much other than some simple excel stuff and get on internet etc. no movies, games or anything like that. would i be better off calling dell or just going to best buy and buying something from there. i cant stand waiting on computers so i want to get something that is going to be plenty of power/speed for what i need. and service would be nice as well. any help would be appreciated. thanks!
