So basically the average user is a power user.
Have you done market research to see how many tabs an average user keeps open? Or what percentage of users want to multitask on an iPad anyway? Or even know that it is possible to multitask on an iPad?
I don't know. Perhaps, like many here, they don't really use tabs. But what is more likely, is that they are not constructing a post in a web forum, switch to another tab to research, then come back to the original tab that is refreshing to lose all they had typed.
In other words, it's an issue that only bothers people who post on forums. Meaning, complaints about this issue is going to be over-represented on internet forums. People who don't post on forums, which I'm guessing probably vastly outnumbers those who do, wouldn't care.
There is BIG hollow area at the top of my iPad Air. They could use that empty space.
That big hollow area contains wifi, Bluetooth, and cellular radios, I believe.
