What does the "SR" in "SR MBP" stand for?
Santa Rosa, though I'll let someone who's a bit more experienced with mac hardware explain the oddities of the naming.
When referred to here its probably safe to say its referring to the 2007 MBPs.
(Its an internal reference to the 2007 MBPs because they had the new chipset from the Santa Rosa platform (and the regular SR Macbooks had the x3100 (and even then its not a true Santa Rosa laptop because it doesn't have the intel wireless card)) While the early 2008s used the same chipset they are often called Penryn MBPs, and are not generally referred to when people say SR MBP. The newest MBPs use the Penryn processor, but are generally refered to just as the New MBP or unibody MBP.) (someone will have to correct me if i missed something/misinformed, I'm more of a software/coder type then a hardware type.)
