I purchased Acer T230H from an Amazon rival simply because I required it rapidly and it wasn't available. Obviously, I paid out more for both the product and delivery. Now, I see that it is again available on Amazon with significant discount.

Pros:
1) In the time of acquisition, the Acer T230H was the one of the largest multi-touch screens readily available. I think still is.

2) It reveals the multitouch features of virtually any Windows 7 laptop or desktop computer.

3) This may be transferred from pc to pc when needed. We now have examined it on both laptop computers and desktops running Windows 7 and it works perfectly.

Cons:
1) I was unable to finish the calibration program during setup. I had difficulty getting the T230H to identify the lower left calibration corners making use of a stylus from a Windows XP Tablet computer. I terminated calibration and used the default configurations. The T230H scans the lower left corners good with its factory settings making this truly no problem.

2) The device is a lot more costly than a standard 1920x1080 display. I'm certain it will drop in price as more distributors carry it.
