There is currently nothing to be excited about. As one press story said

At a press event in Los Angeles Monday afternoon, Microsoft announced an eye-catching new tablet computer but didn't specify what it would cost, when it would go on sale or how long it would run on a charge. What could possibly go wrong with that?

We don't know how crippled the operating system will be, why they used the same name from another product from 2007 (kisoks with touch screens). The keyboard cover is no big deal, I see people with ipads using them all the time.

Not letting the reporters actually use them at the event, just hold them, also is not all that encouraging.

There are many holes they need to fill in before anybody has any reason to get excited about them.
