I hate to say it, but I told you so... I correctly predicted that the Mac App Store, if such a thing was to be made, would NOT be the only way to distribute Mac software. That said... I share many of the concerns voiced in these comments. I also have to wonder what else Apple will unveil regarding Mac OS X "Lion" later.
Mind you, my current Mac came with Leopard, and it feels... how shall I say this... not up to speed with Snow Leopard installed on it. So, I'm going to get a new one that comes with Lion preinstalled. (Yay, more revenue for Apple.) The question now is one of timing, namely, given Apple's roadmap for Mac OS X and Intel's roadmap for processors, which conjunction makes the most sense to jump on? I'm honestly not sure. Sandy Bridge looks awfully tempting, but the built-in video encoding support is limited to VC-1, cutting off Mac and other non-Windows OSes from benefiting. So then, looking beyond Sandy Bridge, the picture gets a lot murkier. Next up is Ivy Bridge, then Haswell, then Rockwell... I'm currently leaning towards either Ivy Bridge or Haswell. Rockwell, as nice as it looks, is just too far out to wait for.
