Atom based tablets .. performance/heat/battery life questions

Anyone try any of the Atom based tables? I am specifically interested in knowing if they suffer form some of the same lag issues as the RT based tablets. As far as i know these same issues are not present in Windows8 with i5 based tablets.

How hot do these tablets get compared when performing day to day operations with multiple apps open at the same time. Do Atom based tablets have fans on them?

Finally how does the battery life compare to the RT tablets. I know from reviews RT tablets are around 10 hours while the i5's based tablets give you 5 hours. Is it somewhere in between.
