offline mode will hardly represent the final product

As long as it is better than WiiU's OS Day-1 I don't see a problem. Took Nintendo almost a year to get it right, so I certainly won't judge MS too harshly now.

Exactly.

And when you are on a demo tour, this is not the best example to show off what your brand new, high-en system can do :?

I re-watched the video and you're right there is a slowdown at the end. Not that it surprises me mind you, I fully expect slowdowns like that in the finished product from time to time because I've yet to come across an operating system that doesn't at least occasionally get laggy or slow. But hey as long as it's better than the 360 (which I think is almost unbearably slow, sluggish, and laggy most of the time) then I'll be quite happy.

Why bother really, that looked like dog shit.

Doesn't look that good. But then again the console has not even launched and even after it has launched, things like this can be improved quite a bit.

Anyone notice they guy, the doing doing the browsing? Notice how he's touching the controller like he's obsessed or something!?

The offline dashboard is never a pretty sight. 

Promising

I think many are missng the point of the dash.

Its customisable. Size of tiles, Faveourites etc. Anyonne with WIndows 8 or WP8 will know that mine will be customised to me and yours to you. Looking vastly different.

Buy or go to a phone shop and look at WP8 phones. They look dull and lifeless. Own one or see someones customised WP8 and it is alive and beautiful.

looks... worse than i expected, and i wasnt expecting much since i hate windows 8
