Since Windows 8 is fairly new, the store is pretty light. I cannot wait until more companies release apps catered to Metro UI, that's when it is really going to take off.
Good apps of bat,
Netflix
Xbox smart glass
Google search
Tunein radio
Skype
My only gripe is that I'm running the os on an 27 inch iMac, they need to realse an updated catering to video/graphic drivers issue.
lol figured u would say those, i have all of those already, they did a nice job on the skype
