HeresMyAccount: Even if it only works like a mouse, that would still be good, because it could be used like a touch pad while also getting the ergonomics of a gamepad.
In that default mode though, can I use the analog stick and have that and the rest of it recognized like a standard XB controller, or do I need a custom configuration for that?
If I do need custom configurations I could go on a different computer and download or make them, then copy them to the other one, right, so it shouldn't be a big deal, just a little more work.
See Nirth's post above, it is not seen as a standard controller, but the mouse/keyboard functions it does have might be enough to replicate one.
EDIT - Bear in mind, that is with the latest firmware, which the controller is not likely to ship with, so you will still need Steam to get that functionality.
