No offense, but that doesn't sound like a smartphone. It sounds like a regular old phone with a touchscreen. Nowadays there are a ton of normal feature phones that will decode mp3s and include apps to check gmail and the like. The design looks kinda cool since I guess the all-screen candybar has become the form-du-jour thanks to Apple's offering. I just doubt it will be much more than the typical phone with a nicer screen.
edit: OK I clicked the link and saw that it is running Windows Mobile. I take it all back
