Is this Microsoft's attack on the App Store?
"When I hear about 600,000 apps, I’m just in awe. As I’ve said many times before, however, I don’t think it’s the right number for comparison. Nobody is using more than a couple dozen applications on their device."
Even If I don't count the many games and educational apps my kid use I still see many more than a couple dozen apps that I used in the last week on my ipad.
Also I don't think hooking a mouse to a tablet is a great feature for surface. It just shows me Microsoft doesn't know how people use tablets. Perhaps they should goto a coffee shop and look at all the people using there competitors tablets. the keyboard can make sense if you type large emails or even do word processing, but I would guess most don't use physical keyboards enough to need to purchase one.
