Yes. The keyboard problem is a big one. It was so painful that I had to buy a bluetooth keyboard just to work with my iPad. That's a hard one to solve until apple comes up with something better user input device. (e.g. thalmic labs, leap motion etc). After I bought my keyboard, the next problem I hit was the inter-app communication issue you raised. That's a software problem and solvable.
