Oh, Eldar, just what are we going to do with you? The Russian behind Mobile-Review.com apparently got his hands on a very early version of Windows Mobile 7 and talked about it on (where else) Twitter. He mentions that "Zune HD is more simple UI) and that "for WM users it will be a great step ahead. For market it's a copycat of Android 3.1/3.2 [ed. note: Android's currently at Version 2.1] or iPhone" with "a lot of horizontal movements, a lot of additional info by clicks etc."
And the kicker, which you see above, is that it might well not be compatible with current Windows Mobile applications. That's something we've been hearing for a while now -- a clean break from kernels of days (and years) past. And while that's not necessarily a bad thing -- fresh start and all that -- if it's true, it'll be sure to upset a portion of the current cadre of developers. Or, maybe they'll appreciate a clean start, too. Glass half-full and all that. Stay tuned, folks.
