It still would have been easier to just use regular sim cards. And most of these carriers are "considering" it for the iPad and don't have it yet. I think only AT&T, T-Mobile-US, and H3G have them.

I was just reading an article that says you could cut your current sim card with no problem for it to work as a micro-sim.
