I'm writing this on an Early 2011 15" Macbook Pro, which is frankly on it's last legs. In fact, it's at the point where I can't really move it around.
It would have been pretty unusable years ago, except that this is one of the last Macbook Pros that you could upgrade the RAM and harddrive on. I got this thing with the least amount of RAM and cheapest harddrive I could, and as time went on I added more RAM and an SSD. New lease of life. And that stuff all cost me about $250 rather than the extra > $1000 Apple would have charged.
I want (and pretty much need) a new laptop, and Apple makes great ones. Yeah, people say "Apple Tax!" a lot, but spec-for-spec, Apple laptops are pretty much equal to other manufacturers and the *usability* is *phenomenally* better. From the UI design to the friggin *trackpad*.
But if I can't upgrade my own machine... sorry, not happening. And that goes for any other laptop maker.
