No, it really isn't. I mean, its not going to catch fire and it probably won't harm the CPU, but increased temperatures are TERRIBLE for your battery. And realize, you will NEVER be able to replace the battery in this tablet outside of the first year.

Also, your battery life will be pretty crappy while the tablet is hot.
The Arrhenius equation defines the relationship between temperature and the rate at which a chemical action proceeds. It shows that the rate increases exponentially as temperature rises. As a rule of thumb, for every 10 °C increase in temperature the reaction rate doubles. Thus, an hour at 35 °C is equivalent in battery life to two hours at 25 °C. Heat is the enemy of the battery and as Arrhenius shows, even small increases in temperature will have a major influence on battery performance affecting both the desired and undesired chemical reactions.
