Honestly, I think across the board, computer and accessories prices are much more expensive in Singapore as compared with US, even after factoring in the exchange price difference, plus shipping and insurance (if you are kiasu enough).
Back to the Z930, I noticed it's shortcoming, especially on the keyboard portion. At the same time, after carrying it around in my backpack, my Z930 is also starting to warp on it's back, especially I lie it on a flat surface, one of the corners is not flush to the surface. Not sure if anyone has noticed it or am I the only one facing with this issue?
As for fan kicking it, not just playing games, but when some of my scheduled maintenance tasks kicked in, the fan will start to spin. Needless to say, without a dedicated onboard GPU, playing games on Z930 sucks...
Like Shawn, I have also recently upgraded to Win8, but I went the simple way. Total wipeout and start with fresh install... Drivers which I have downloaded from Toshiba UK works perfectly, especially the touchpad drivers. Multiple fingers gestures work fine after you get used to the sensitivity... although the glass clickpad on Apple is still the best...
