Remember those old, allegedly leaked Windows Mobile 7 screen shots from way back in 2008? You know -- those ones that look absolutely nothing like the so-called Metro UI that Windows Phone 7 Series is actually using? Well, Microsoft's Albert Shum -- one of WP7S' chief designers who we had the pleasure of meeting back at MWC -- just confirmed the accuracy of those leaks in a session here at MIX10. Discussing the reboot of the WinMo 7 program that happened inside Microsoft about a year ago, Shum flashed a slide showing eight of those infamous shots featuring those crazy bottom-aligned battery and signal meters along with WinMo 6.x-ish ID oozing from every nook and cranny. Needless to say, a clean-slate approach was sorely needed, and that's exactly where Metro ended up coming into play -- but be honest: is there anyone out there that would've still preferred the old leak in a production device?
