I will be first to admit I have addiction problems.
First addiction: Foo Fighters
Love 'em, need 'em, follow 'em, Google 'em!
My current obsession/addiction is as follows--
If I ever get bored with the design I'm currently using, then no problem, they come out with new artist works all the time! Not to mention they have new devices they create skins for almost weekly.
A new feature I'm hoping to try soon is their "Create Your Own" option that allows you to chose your own art for your device.
If you have or are looking to protect your purchases I highly suggest checking these guys out!
Their fast, friendly, and just simply put AWESOME!
