I bought a MBP15 (early 2011) last July and it sucks. Runs hot, freezes, won't wake from sleep, etc. Geniuses didn't find anything. Called Apple and went through 4 levels of support and best I could get was offering a discount on a new machine or sending the old one in for more extensive testing. I'm past trying to find fixes. I want to know how to get Apple to replace the machine. I'm not trying to get a new model. I just want a new version of the same machine. Any advice on how to make this happen?
