While they certainly want to create an editor for the PC, one does not currently exist and, in fact, one is not being worked on either. So it will be quite some time before anyone is able to develop ON the PC for Unity. If you have a Mac then you can develop using Unity and make cross-platform games with it.

There are a few options here if you don't have a Mac: 1) Buy one of the new Macs on Intel hardware and then install both Leopard and XP/Vista or 2) do some research on installing Leopard on your current Intel PC (yep, there are some ways to do it but, be careful, not every way is legal).
