Reply to iPhone:Tonetable

I stumbled onto a very interesting piece of APP yesterday while browsing-
a litte piece of code called Tonetable, which emulates a control-vinyl on your iPhone/iPod Touch. It claims to be able to emulate not only Traktor Scratch Vinyls but a number of other DVS' as well. Never having used a DVS I became interested and made the purchase 5 Euros just out of curiosity. And even though I can only demo (didn't know that Traktor Pro != Traktor Scratch Pro... so much for the system of Traktor 3), I demoed it shortly and found it to be rather interesting. Not the feel of real vinyl obviously, but with a pitch-band, a key-control and a rather nice emulator of a TT, it interested me enough to ask around here if someone with more experience in this field has done reviewed this?
