Well, it's not just a finger groove...it's their version of the Apple touch wheel, and apple does have an "OK" button in the middle of their wheel, they just didn't label it. If their touch pad keeps scrolling as long as you're applying pressure up or down, then it should work fine, but if you have to keep picking up and re-swiping your finger, it's not going to cut it.
This thing doesn't make me want to trade in my iPod, but as copycats go, this is about as nice of a device as I've seen. They just need to bring the size down a tad more to match the iPod. In "pocket devices", every ounce counts.
Edit: I guess they're at least providing a nice feature with that extra weight and thickness...24 hour battery life. That could really make a difference for some on-the-go people.

I love the "Ok" button.
It even has its own finger groove. Something about it is just making me laugh...
