I am thinking about purchasing one of the early releases of the MBP 15", before they replaced the expresscard slot with the SD Card slot. As a filmmaker, the expresscard slot allows on-site ingestion of Sony's and Panasonic's SxS and P2 cards - a nice utility. I also don't use point-and-shoots, so the SD card has zero utility for me. I just wanted to make sure that, before I buy the previous revision, there is nothing I will be missing by purchasing the older edition. I remember that they widened the color gamut on the MBPs by 30% with the update, but this is really insignificant as their color accuracy isn't thaaaat great anyway. This is the laptop I am considering - http://www.amazon.com/Apple-MB470LL...f=sr_1_11?ie=UTF8&s=pc&qid=1249594761&sr=1-11 But I just want to make sure I'm not missing out on anything massive, like, say, they added another 3 hours to battery life, or, they fixed a hardware glitch that causes the disk drive to spin out of control in every 1 out of 100 uses. Please let me know your thoughts on this, and feel free to let me know if there are any cons. Thanks!
