I'm glad somebody else caught onto the fact that there are 3 connectivty types (WiFi-only, ATT WiFi+3G, or Verizon WiFi+3G). What is funny is one only need look at the order page to see 3 groups of 6 models.
Ironically, everybody always says Apple is overpriced and offers you no options. This does not apply to the iPad. It has an incredible price in the tablet market and gives you 18 choices. Much better than Moto is currently offering on the Xoom with one high price, 1 color, 1 capacity, 1 carrier, no WiFi-only option (yet). The typical Apple complaints don't seem to apply to iPad. You can still complain about the ability to "trick" it out like Android. But it all depends if you want to buy something you just use or something you want to tinker with and customize. Apple is foregoing that latter market while still giving the former market the kind of options they are looking for.
BTW... they also offer 10 options of smart covers (2 materials x 5 colors each) with a total of 9 distinct colors since (since two are black) -- or 8 if you think those grey colors are close enough to count as one.
