My current Android tablet set up using SS Launcher, with a bit of a Metro style. SS Launcher is the most customizable Launcher available and the best for creating a "Metro" look. It swipes in from the right side with similar animation to Windows 8 as well. If there's enough interest, I'll put together a tutorial how to set it up.
Top View is Page 1 (Starting or home page) Time, Date and Weather widgets were made using Ultimate Custom Clock Widget (UCCW). Agenda is Pure Calendar widget with custom skin. These app shortcuts are the most used
The two middle views are pages 2 and 3, swiped from right: The wide shortcuts are my app folders
The bottom view is it all put together
The vertical bar on the left is not a dock bar or special app. It is a widget, made using UCCW again, and the shortcuts are for Tablet Settings, Launcher Settings, and SS Launchers App Page. Unlike a dock bar that is always in place, this widget had to be placed on each page separately, although it is barely noticeable when the sliding animation transitions you from page to page.
All of the icons, backgrounds, widget skins were all made myself, usually with Illustrator
