Serato Remote - Ipad App

Check out this video from Serato which shows the functions of the Serato Remote. I'm not going to lie, the idea is pretty cool but I doubt it is going to replace some MIDI controllers. The reason for this is that while using regular MIDI controllers you can see and feel what's going on. This, being a touch screen and all, will take time for some to get use to it. Let us know what you think about it? Will you buy it?
