If you listen carefully you can hear the typing on thousands of keyboards as web folks get their sites ready for HTML 5 for the iPad.
You can also hear the typing on thousands more keyboards as programmers adapt their iPhone apps and are trying to code the first big app for iPad.
All of these people are able to evaluate their work on the iPad simulator that comes with the SDK.
Never in the history of computing platforms has there been a platform that launched with so many web sites tailored to it and so much software written for it before the first day of release. I have not heard people commenting about this maybe because it is just the environment we live in. This platform advantage is huge.
