Trying to read Steve Jobs's mind, I'd suggest that there won't be a new Mac Cube or anything like it. Otherwise, they would have done it years ago. Instead, His Steveness wants to sell you an iMac as the standard desktop machine, a Mac Pro if you really want serious crunchies, or a Mac mini if you're a cheap bastard. That's it. If they released something akin to the $1000-2000 consumer PC line, it would cannibalize sales of both the iMac *and* the Mac Pro.

Which is precisely what is pushing me toward getting a Hackintosh desktop of some sort once 10.6 comes out.
