Not me but it looks interesting. I do own RBCN which has been one of my duds. They make sapphire crystals for the LED, silicone on sapphire, and optical window markets. The price of the wafers has dropped very significantly and only recently has the pricing started to improve. I would not know if this has also affected GTAT business also.
I really liked the HIMX CC. I sold some at $7 and bought some back in the lower 6s. I am hoping to buy a lot more if the price dips again. The existing businesses seem to be doing well even before Google glass will start to impact results.
