I got my 2011-model 15" MBPro (256GB SSD with 8GB RAM and i7) early this year before the current 2012 MBPro model became recently available. So far, my experience with the 2011 MBPro has been positive except for the following: 1. The machine can get to be very hot so it's near impossible to have it as a laptop 2. The lack of USB3 ports is limiting my options in taking advantage of fast, expandable, external hard-disks/SSDs 3. The lack of a HDMI port is a pain (but it can be solved with a special cable?) 4. The machine is rather heavy Now if I were to consider replacing my 2011 MBPro with the latest available MBPro (without the Retina Display, which is not important to me), would my above negative experiences go away? Thanks for all advice.
