According to Valve's big boss, engineers are still working out the kinks, mainly balancing power with heat and noise:
"There are noise issues and heat issues and being able to [deal with] that while still offering a powerful enough gaming experience is the challenge in building it."
A tiny box is cool and all, but if it makes a right racket with the fans going full blast all the time, it'll be a bit crap -- we certainly don't want a repeat of the hairdryer Xbox. Anyway, Newell also talked up the rumoured bio-sensors in the controllers saying:
"... you need to actually be able to directly measure how aroused [scared] the player is -- what their heart rate is, things like that -- in order to offer them a new experience each time they play."
It sounds like Valve's looking to make the Steam Box a homerun in the first instance, which is a good sign. Everyone seems to be going nuts over the idea of the Steam Box, and considering the likes of the PS4 have just turned into a glorified PC -- a relatively underpowered one at that -- Valve really could have a decent shot at revolutionising the console market here. Let's just hope it's cheap. [BBC]
