And then it gets into the "vista vista vista! omg!" stuff, which is misleading. Yes, some cool stuff is in Vista wrt memory management, and if the HHD exposes information which lets the vm system in the kernel do smarter shit, great. But 1) if there are/were open specs to the disk, it could work with any OS, and even if not, people will figure it out, and 2) there's no reason the harddrive can't still look like a harddrive and work with any OS, and still have a lot of advantage from having a bunch of memory inside.
Hell, I bet the "HHD" just shows up as two SATA devices, one typical disk, and one flash, and all the magic is in Vista, not in the drive's controller.
Rant, rant, rant.
But at least we'll finally be getting non-volatile memory into our laptops.
