Got this in the mail the other day, but haven't had much time to play with it yet. The software isn't the friendliest in the world but it works. And yes, it works in VMWare Fusion on a Mac. More to come. This is the 915MHz US Version, not sure the worldwide ones are shipping yet.

Gotta love the warning message...

This is the EZ430 Emulator

This is the RF Access Point

To program the watch, it needs to be taken out of the casing. This actually has some modding possibilities instead - putting this on the dog's collar could be fun.

Getting the battery out kind of stinks - had to use a paperclip as the included screwdriver didn't do the job.

This is the watch component connected to the EZ430 Emulator for programming. There's a couple of small SMT components that seem to get in the way when you connect the programming headers, but with a little fiddling it connects.

That's all for now - I'll put up some more on programming the watch, interfacing with it, and so on as I get some time to use it. Looks pretty cool especially for $25 US (Doubt it still works, but MCU2009-06 is the coupon code to try.
