By later this afternoon, we should all finally learn what Microsoft's announcement will reveal and the plan for a tablet should be confirmed. For now, speculation is that it will align with their recent investment with Barnes and Noble and synergy with their Xbox product. The Xbox makes perfect sense as I speculated in an earlier blog. What capabilities B&N bring are less known; could it be that it incorporates an app to read Nook purchased books, possibly. Or that it will use the retail locations of B&N to sell its tablet; certainly not an exclusive relationship as I'm sure every other electronic retailer, Best Buy included, that will also want a piece.
Is Apple worried, of course not. Without an engine of content behind it, like the iTunes app store, Microsoft will have a lot of catching up to do. The Xbox angle will help, but I wonder if it will be enough.
