I always wonder if it's a better strategy for Microsoft to introduce the Windows AppStore in Windows 7 first and grow the eco-system there, just like what Apple did MacAppStore to Lion, heck, even 10.6.6 (Snow Leopard) has access to it. Oh, well, perhaps the higher-ups in MSFT need to have a clue first.
