Support for Dell Canvas?

I don't know, but I hope it comes eventually.

The totem looks really similar to the Microsoft Surface Dial (or whatever it's called). I hope they all use the same underlying interface with the OS. Otherwise no software manufacturer is going to take the time to make a custom menu system for each manufacturer's little puck thing.

However, if they all use the same interface with the OS, this would be a great thing. You could have hyper-context-sensitive menus which make working with the software much more streamlined. Plus it just feels cool to use!
