Jsut a thought on glassless 3DTVs, they're likely about 3-5 years away yet before they come into play (strictly due to the expense to manufacture) , and another 3 years after that before they become affordable.
As for cell phones/smartphones, even now they're kind of clumsy for gaming except fairly simple/casual games, imo of course. Others may feel differently.
