My 2008 Macbook Pro (unibody) is getting old and sometimes blacks out while playing games. I am looking to purchase a 2011 Macbook Pro... If there are enough new features to merit the $2400+ price tag. Any ideas? Will it support USB 3.0? Will it support Lightwire (or something like that)? Will it have a better graphics chipset and the i9 Intel processor? More RAM? Better (IPS) display? Optical drive? Thoughts?
