I feel for all the customers who stuck it out with those defective nvidia GPUs. I am personally please Apple has moved to ATI for everything but the Macbook products (and the mini). After the 8600 mess I'm amazed there are still people advocating nvidia in these very forums. I'd be fine if Apple never used another nvidia product. I sold my SR 2.2 after 18 months and 1 repair. Those folks who've stuck with those machines through many many repairs should just get a new MBP at no charge.
Cheers,
yes I just got my 15" early 2008 king sized to a i7 17" last week, though my "straw" that broke the proverbial camel's back was unrelated to the GPU (though i've had it once before) .
So keep on them. Four years is a good amount of time to rack um the repairs.
