You can also right click on metro UI tiles and resize them on a PC and there's some limited ability to run metro UI apps in a window on the desktop side of things, though by most accounts it is more of a preview of what's to come rather than a ready for prime time feature.
A future update to 8.1, presumably the one after the one set to roll out to everyone on the next Patch Tuesday, will be quite interesting however. MS demoed it a bit at their event yesterday and not only does it fully restore the start menu, but the right half of the start menu will now have metro UI live tiles on it, finally making at least some effort to try and merge the two in a way that's actually useful on a desktop. You can also run metro UI apps in a window on the desktop side of thing and this time they appear to scale to the size of the window, unlike Update 1.
It's taking them a while to get there, and it can certainly be argued that they should have had some kind of plan for how they were going to use the metro UI on the desktop before launching... But Windows 8 is shaping up to potentially be the new Windows XP. In that everyone had nothing but contempt for it when it first launched, but as people had time to adjust to it, it became the new normal to be pried out of their cold dead hands.
and there aren't that many changes. I just played with it a little bit and here are some of the things I noticed.
1. The Store shortcut is on the taskbar on the desktop.
2. Search and power shortcuts in the Metro Start screen.
3. X in the Metro windows click options
4. Taskbar on the Metro Start screen that hides when you move mouse.
5. The taskbar looks more like aero in Windows 7 and translucent.
The update will be a series of Windows update next Tuesday. I got the updates from Technet and it was a zipped filed with about 6 update files that I executed one at a time. Most of them required restarted after they install so it restarted around at least 4 times.
