I can only speak to my situation, but as the macs took longer and longer to update, I came to the realization that I might need to jump ship. And as the upgrade wasn't entirely reassuring, it seems like it might be better to bite the bullet and switch to linux full time—which, incidentally, I'm also pretty excited about and want to do. The anger/frustration about the new models is about accepting that my time with the mac might be over (a ride which I began back in the OS 8 days). However, seeing how disappointed I've been has only strengthened my resolve to switch as I don't feel I should become that emotionally attached to a company or product (I went through the OS holy wars as a middle schooler, so I can forgive it as a folly of my youth).
