In the OP's defense if I didn't already have my iPad2 I'd be wondering how this might affect availability. I doubt that I'd voice this concern on a public forum, but it would certainly have crossed my mind. I'd be more impressed if those who responded to this thread proposed doing something constructive to help the situation rather than dog piling on the OP for being insensitive. Beating up on the OP is not going to help the people of Japan, if you want to help, help, otherwise your no more sympathetic to the situation than the OP.

Yes, you are right. People should donate.
Of course we all thing about the availability of the iPad, we just try to be not that upfront. I also have an iPad 2, so I don't really care about the availability of a device I already have.
Anyway, let's hope that Japan will make it through this unbelievable catastrophe.
