I've got an Asus Transformer TF-101. I use it when i travel and take it with me to work to watch stuff on while im working. The battery life over a laptop is the biggest gain i notice. For instance, today at work i've had episodes of Dr Who playing from 8:30am until now 2pm and it's been off battery power alone. I've got 47% charge left (I have the dock that goes with the transformer which has another battery but it's drained right now)
I tried to watch a couple of episodes on my laptop unplugged and i got halfway through the second before i got the critical battery warning.
That said, i use my laptop primarily for downloading media and then i move it to my tablet or an external hard drive just because it's easier.
And my tablet never gets hot enough to disturb me in anyway
And they just updated the firmware to Android ICS 4.0
