Since you chose to ignore the other part of the post... As an owner of an ipad 2 and an ipad 3 and a laptop, you're wrong about the temp issue. If anything a laptop on my lap is far more uncomfortable in terms of temp than my ipad has ever been. I'm not trying to convince you to buy one, but your post is nothing more than guessing on what your opinion might be if you actually used one. Unless you've got abnormally sensitive skin, its not an issue.
As to the charging issue, I know lots of people with iPads and other tablets. Not a single one charges it while they're in use. With a 10 hour battery life, people use it and charge it over night. When you get up, it has a full charge. There really is no issue. I realize this is anecdotal evidence, but I highly doubt the people complaining about charging during high usage actually find themselves in such a scenario, including yourself.
Essentially what I'm saying can be summed up into one sentence. If you're a normal human being, the only time you'll come across these issues is by reading about it on the Internet.
