I'm not scared of nano tech at all. I want to never have to carry a purse or wallet again; implant all of it [credit cards, drivers license, ATM card/bank account info, birth certificate, etc.) in my arm, I'll wear an RFDI bracelet no prob. I want an eyeball "mounted" heads up display so I can look stuff up no matter where I am, network it to my computer so I can leave myself notes and stuff while I'm running around. I want a brain controlled computer interface, I want to think my cursor around the screen and more. Give me nano medical bugs that you swallow and they swim around fixing everything. These things are awesome to me.
I am 100% geek and addicted to my computer no doubt. I've had a computer since 1986 or something like that, I build them, I mod them, I speak their language.
