Before the iPad came out, I was drooling over Microsoft's Courier tablet. It was exactly what I wanted in a tablet. I made fun of the upcoming iPad because of the Courier. Then, of course, Microsoft bailed on the Courier, and I ended up loving my iPad. Having an app that features the functionality of the Courier on my iPad would be freaking awesome.
It sounds like the company has funding, but it will be awhile before the actual product hits the app store (if it even does.) I'm crossing my fingers.
