I have a MBP purchased new with Lion installed in June 2012. Had the dreaded ? folder appear after a restart the other day and discovered I couldn't use the internet recovery option. After spending well over two hours on the phone with senior level tech support, they made an appointment for me on Wednesday at the Genius Bar (four hour drive round trip). This MBP is only three months out of warranty. So I am currently using my 2006 MBP also running Lion. This appointment will be interesting to see how they handle the failing hard drive and what OS they replace with.
