It's a shame they couldn't release the iPads with 4.0 on them because many of the non-technical people won't realize there's an update or no how to update it. Though I guess last time they did an update along with a major device release (iPhone 3G) it was pretty disastrous because of all the hits on their OS and activation servers. Maybe they should have not required iPads to activate via iTunes.
I would love them to make two changes for 4: OTA updates and syncing to mobileme or a USB hard drive. If they did those two changes, it would open up more people to be able to use and iPad.
I suppose so if you never want to do any updates or get media onto or off of it. Apple lists iTunes as a requirement so I don't think I'm exaggerating.
