Transmeta is currently working with Microsoft apparently on the Tablet PC. Sony is using the chips in a few things, other companies are still looking into the chip. One is releasing a notebook with a Windows/Linux switch on the side that controls what OS it boots into.

I just can't wait for their non-mobile processors that can emulate almost any processor out there. I'd love a desktop that can switch from running Win2000, to Mac OS X, to Solaris 8, all on their native platforms. They are taking about the jump to 256 bit soon, and that will allow the Intel emulator they have now to throw 5 instructions through the chip per clock cycle. (8 in theory, but 5 in practice).
