I just picked up a refurbished 27 Acer touch for a bit over $400 with shipping from AMAZON... I already have the 23 inch ACER that I thought I would use to try touch.... which I have found I love but just a bit too small for my needs (I am getting up in age and my eyesight isn't what it used to be) and hope that this monitor will be a bit easier for me to use. I plan on going dual touch with my SONAR DAW.
However, I have found that some functions are easier with the mouse so even though I have touch and use SONAR in a touch/mouse/keyboard dual function mode. CONTROL S to save on the keyboard, mouse to LOAD files and the touch to mix and turn knobs on VST plugins.
As a side note, I have a MS SURFACE RT (which are dirt cheap now) and with WIN 8, can easily be setup to serve as a remote desktop to the DAW and use it in my studio to easily control recording while in the tracking room without going back to the DAW to track live instruments that I play...
Technology is surely getting wonderfully amazing.
