borntobesting: As the OS for the Surface is Windows 8 you can play directly from WGT.com and have all the features of WGT including full multiplayer , match play and A/S.
Exactly.
Although I avoid MS products as much as possible, the Surface Pro is a PC, so it will play just like a PC. As Joe noted, just go to wgt.com and sign in. If you played on mobile before, it will be different but much richer (IMHO) - many more options (excluding the apparel stuff).
