The biggest "Wow!"s will come with the applications developed for the platform. At least the wows people will report on.

In a way i think that is a great thing. MSFT has given the MSFT development world an excellent platform for the future (one that should become far better over time). Devs now have some great tools to really push the ideas of what applications should feel like and to redefine "connected" for the average user.

Personally i never expected more than the true geeks to be excited (i know i was).... average users won't find too many reasons yet to make the jump. In the coming months and years there will be far more compelling reasons as new applications come to the forefront making people finally go "Ohh Wow!!"
