Hate to spoil the pre-unibody macbook pro haters club meeting, but I just have to disagree on one point:
The Early 2008 17" MBP offered a High Res 1920 x 1200 LED as an option. These discrete 17" models continued through the October 2008 introduction of the Unibody 15" model.
I bought mine because they are the [b]last[/b] user replacable battery models ...and the last ones actually take and use 8 meg of RAM. I did send mine off to have the graphic chip replaced with the 2010 model of the 8600M/512MB chip and an SSD drive is in the works.
Bottom line: With the MXO2 and accelerator, it is still a good, usable tool. Also, it you shop carefully ...you can find good used ones (with the hi res screen) for under $500. (I've since bought spares.) Spend another grand on a few things, most of which will transfer to newer machines and you are home free for really cheap, [i]AND[/i] you can also use it on location for HDMI out ...just take along some extra batteries!!
