Replying to Another Computer thread

My Dell finally crashed on me and I am looking for some advice on what to buy next. That thing gave me nothing but problems and I would like to invest in a mac but without breaking the bank. I dont use my computer for anything special just school and whatnot so I dont need anything fancy. I dont know much about some computers as you can tell so I just want some advice before I spend anything.

Help me out +k for any helpful information!
