The positioning made it unwieldy and that it was made of glass and seated above key components made it uncomfortably hot to the touch -- awkward at best and potentially infuriating for a $3,000 machine. As such, we're relieved to see Acer take a fresh approach with the Predator Triton 900, whose touchpad sits to the right of the keyboard, remedying the fatal design flaw of its predecessor.

We clocked Predator Triton 700's glass touchpad at over 118 degrees during our testing. Ouch.
