There is no VS for WinRT - but if you have a full PC and an RT tablet you have the perfect dev environment as you can set up the RT device as your target for development purposes (ie when you hit F5 you deploy over your network/wifi to the tablet).  This works surprisingly well and IMO is preferable to using the emulator/VM device on your PC .

touch+hold = Right Mouse on the legacy desktop (I don't think it is relevant for the 'new' interface)

Sorry Sven, just noticed this was aimed at you.
