Also, it would be interesting to further investigate where those ‘unrealistic expectations’ come from. I’m aware it’s not a huge statistical sample, but considering the people I know, online and offline, who own an iPad, and considering the people I’ve helped with their iPad, virtually none of them has manifested dissatisfaction with the device in an ‘unmet expectations’ kind of way. Everyone I know seems to have been aware of the scope of the device when they purchased it. They knew or understood what they could and what they could not do with it. There has been the occasional nuisance, but nothing that can be considered a ‘deal breaker.’
It's important to keep in mind that, despite all the things iOS could do better, we shouldn't confuse the average iPad customer with tech bloggers trying to use WordPress on an iPad.
