I get the ad, I just hope they release better ones.
Yes I understand that it has a cover that's clickable, but I didn't see 'why' I need one. If I'm a consumer and I have 3 choices (iPad, Nexus 7, Surface) I know what an iPad is. The price of a Nexus is very tempting, but what does a Surface provide other than a clickable cover?
They didn't show why you want one, why you need one, what you can do with a keyboard that's also a cover other than you can dance with it?
I hope future ads are clearer.
