my keyboard is rock solid so far... and no dust...

but I can see how dust woudl get in there...on the side of mine, below the USB and hotkey, where the black side trim meets the front case - there is a large gap..where light shines out even. lots of dust getting in there...and I assume making its way up the sreen. :( oh well... Ill use it for 11 months then request a warranty exchange
