If you're just browsing its not much hotter but if you doing anything which really stresses it, it can go 6-7c hotter taking it to low 40c which can be quite uncomfortable.
Same thing with the battery life, if you run at lower than full brightness (which in most cases you will) the battery isnt too bad, but at full it drains down pretty quick.
As i said before, the problems are definitely there, its just if they will actually affect you depending on your usage i.e. are they problems for you or just other people with different usage patterns.
Most other tablets dont cost as much as the ipad, so lower standards are to be expected. Macbook pros are not tablets, so are irrelevant.
