I really don't understand why this is crazy at all. Clock speeds haven't been useful for years in determining your overall system preformance (have they ever, really? There are so many numbers involved in getting a meaningful picture of performance for almost any computing device that putting that information out there would confuse most people.

Furthermore, you can't just run almost any OS on the iPad anyway (like, say, you can with a Mac) so it's not directly relevant as say, on a PC.
