I'll put my Acer against any other laptop here. Benchies anyone?
If you run a powerful dual core (or even single core) system at 100% CPU and GPU utilization your system will get hot, no matter who made it.
Acers are amazing and a very good buy. My system (before the T7400) was less than $1100.00 out the door. I have not seen a better deal anywhere for so much capability.
You can stick your Dells and Lenovos where the sun don't shine. And the person who claimed the X2 Turion is old tech is obviously a joker, or at the very least uninformed.
My Acer is a monster. I couldn't ask for better! To buy something else just because Acer has a reputation for building inexpensive hardware is rediculous. I was so impressed with mine I bought two more.
