I picked up the 13inch Macbook pro on Oct. 22nd. Since then its been working fine EXCEPT ( I just noticed a few days ago) a bad wobble when on a flat surface. I didn't notice at first because I would use it on my lap or on the box it came in. I do have a couple of questions though about bringing something like a laptop in to the genius bar. 1.) I would rather not get a NEW Mac if possible. Does anyone know what the odds of them being able to give me back the same one? 2.) I have some important stuff on here, do I need to delete everything incase they DO want to take it back and give me a brand new one?
