Theory #1

Apple had already reserved their usual building for their announcement. The date had been set, and things were in motion that could not be reversed. Unfortunately, they couldn’t get all the bugs worked out of the software, or necessary patents, or whatever, with all the features they were planning on putting in it. And since they couldn’t demo a product that didn’t function properly (or might lock up or something), they had to “pull” those features out of it and not say anything about it. Instead, they will release iPad v2 this fall right before Christmas with these missing functions.

Theory #2

Apple intentionally left stuff out of the keynote. They knew that by the time it was actually out and people could buy it, the buzz would’ve died way down. Also, they have lost all the impulse buyers by not releasing it for 2-3 months after announcing it at the keynote. So, in order to regain excitement and pull those impulse buyers back in when the iPad is officially available for sale, they are reserving the announcement of its full capabilities. This means that in March when you can officially purchase the iPad, Apple will be announcing that it does include things such as a camera and multitasking–just to name a few. All of a sudden, the iPad is back in the spotlight. The media is going bezerks and everybody and their mother wants to get one.

Just a theory. Only time will tell.
