Thanks for the link!
A friend showed me hers for about an hour last week. Very nice tool/toy.
This article added to that experience by noting that there is a credit card reader app available - https://squareup.com/
- I was looking at spending nearly $900 for one of those, and that dang near pays for the ipad
BTW, Ben, the remote access app is a great tool. I've been using variants of it for a very long time.
