Is anyone office using/planning on using Patient check in tablets?

I was wondering if anyone has or plans on using patient check in tablets? I have been trying to look into getting check in tablets to use for this office and would like to know if any other office has been using or is looking into using an electronic check in system? With Meaningful Use and the advantages to a paperless office I would have thought that I would be able to get a lot of infomation about them but there does not seem to be a lot of information on them.

I am using Instant Medical History from my website for patients to send before their appointment or a patient kiosk for patients to enter their medical history before a visit.
