I've got 5 different launchers currently installed on my phone and Launcher 7 (the one in that pic) is the only one that isn't obviously Android. It's not like setting that up took any effort either, it's just a single app download from the market.
That's part of the beauty of Android, I can transition between TouchWiz, the default Gingerbread launcher, Launcher Pro, GO Launcher(themed to look like Honeycomb), and a very convincing clone of Windows Phone 7 by pressing a single button.
The large amount of unread email is due to me receiving some mailing lists on both my work and personal accounts. I end up reading all of them at work and then just have Gmail automatically store them under a label in case I ever need to access them in the future.
