Mid-2009 MacBook Pro 13" 2.26GHz Intel Core 2 Duo Graphics NVIDIA GeForce 9400M 256 MB Upgraded online to a 320GB HDD instead of 160GB 2GB DDR3 RAM Battery isn't as good as it used to be of course ~2.5 hours of casual use I also bought Windows 7 Ultimate for it and installed it on a different partition. It's cleanly installed. If I do a clean install on Lion, will it wipe out my Windows 7? Can I sell it with both cleanly installed or no? How much would that raise its price? It has some very small nicks all over the body from regular use. Aluminum is so SOFT! I want to upgrade in Spring when Apple releases the new designed MacBook Pro. How much do you think I can get for this laptop?
