Lora, a MVP behind whatisnew blog has received a TabletKiosk Prototype and she is posting her experiences here.
After I opened IE to check out the browser experience, I installed Skype, MSN Messenger, Audacity, InkGestures, and the Music Composition Power Toy. Within a few minutes I was able to write, "Hello from an Origami," to my family and friends online. As I'm sure you can imagine the responses that I received were fairly excited. People asked, "What do you think? Are you using your finger or pen?" And, questions have continued through to right now.
I can use buttons, pen, or finger to navigate. Since I am proficient at using the pen on a Tablet PC already, I am trying to make a special effort to use the additional input methods. I'll give you an update tomorrow on how well I'm doing. So far, it's simple and straightforward.
