Certain user interface elements of the sundry Windows Mobile 7 mockups we've seen floating around over the years have remained more or less constant -- a general gravitation toward better touchscreen usability and some positively bizarre bottom-aligned signal and battery meters, most notably. WMExperts is showing off a newly-acquired document of some sort comparing screens in 6.5 and what was apparently supposed to be 6.5.1 -- the finger-friendly tweak of 6.5 that would precede 7 -- but those mockups on the bottom there have apparently been pushed forward and are now being repurposed as guidance for 7's visuals. For what it's worth, the mockups look so drastically different from 6.5 (and so similar to what we've seen prior 7 leaks) that we're inclined to believe this stuff was destined for 7 all along -- and it actually looks pretty snazzy, save for those dang meters down below -- but whatever, Microsoft, let's just get this moved to RTM already.

Update: pocketnow.com has some additional mockups posted, possibly from the same batch; it looks like they were playing with the appearance of elements, because the meters have a distinctly different appearance (though they're all still at the bottom). Can you tell we hate the fact that they're at the bottom?
