As you can see on the Kickstarter site (for just another 5 days), the TouchFire keyboard is an overlay that secures to the iPad in landscape orientation and provides a uniquely designed surface that allows you to quickly touch type using the iPad native iOS keyboard. There are clips to even attach the TouchFire to the Apple Smart Cover and you can set it aside when you are not typing in a document. The TouchFire supports the origianl iPad too, as shown in the video on the site.
I may get a chance to meet with Steve this week to see the TouchFire in action, but just based on the information on the Kickstarter site I just ordered the TouchFire Kickstarter Special so I can get a black and white keyboard. Keep in mind that there are only five days left in the Kickstarter campaign and after that if you want a TouchFire you will be placed on a waiting list.
