It's taken 4.54 billion years, but finally Planet Earth has its very own Pocket PC theme. Actually, this theme is one of a number of similar mobile downloads that pay homage to the place we humans call home.
This particular theme is quite well done, although I wouldn't describe it as being 'out of this world.' That said, the image is an OK one of the planet from space, although it focuses on the American side, which I've always found less interesting to look at.
The Blue Planet theme also changes some of the menus and toolbars in Windows Mobile. The transformations aren't revolutionary, but they're pretty pleasing on the eye nonetheless.
If you want to celebrate our homeland on your Pocket PC this theme will do the trick, though I dare say you'll get bored of it before too long.
