Nope, u guys r not alone.. Ive got two in my house, ones mine and ones my brothers both G75vw 3D model..
And on both i have noticed this 'flakey keyboard' as you call it.. Its not that its broken or anything but i do notice that when playing games i have to put a bit more pressure on the 'W' key to move around or sometimes when sprinting in game with 'shift' i will stop sprinting because i did not keep enough pressure on the shift key even though it is still pressed :s
Its weird, but i feel it less evident when im typing.. only when im gaming and have to hold keys down i do notice the flakeyness.. but ye i dont think u guys need to go n return/repair anything.. i think its just the way it is lol.. other than that i have no other complaints about this device, its quite a beast of a rig imo
