I need a replacement fast for my 3-year old macbook pro that fell on the floor. the screen is busted, and it's not under warrantee (white screen with vertical lines that come up to demonstrate the position of the mouse). i'm worried that it will cost a ton of money to fix since additionally the body/lid is dented in several places. in case the apple store says it will cost a ton to fix, should I buy an Air now, or wait until May for ivy bridge? i can also hold out on ubuntu until May, and need a 13 inch, so any alternatives are welcome (i need to finish a thesis on this machine). thanks!
