I am definitely on the fence on this one. I love the look and experience of Windows 8 in the video, but I am worried about all the talk about HTML 5 and not hearing anything about the WPF/Silverlight/XNA story. We have seen Microsoft pick these tools for XBox and WP7, but now will they have a cohesive story that will sell tablets and also sell App builders. The winner this battle with have to have the Apps so I can see why HTML5 is compelling, but it also does not drive loyalty and leads into one code base for iOS/Android/Windows8 and that does not sell tablets.
I have to admit, I wish I had more information, but just like any good movie or book, there is a climax that is hidden from the audience and that is what I expect Microsoft is trying to build up until the BUILD Windows conference in September.
What do you think?
