best video phone

[ritsadmin]

I am looking for a high quality video sip phone (h264/h263) ideally with a tactile screen.
I have tested a grandstream gvx3005 and with the later firmware it does what it says but let's say it's not that sexy.

I'm considering the following but no one wants to loan me one to test !

Grandstream GVX3140 - looks better....no tactile

Snom 870

- But i don't think it has any native video codecs (camera it less important) as typical useage will be to view a mobotix ip gate camera.

Polycom VVX1500

- But no tactile screen

Nortel 1535

looks nice but no tactile

Any comments on any of the above phones or some good alternatives known to work with the quadro would be welcome.
