"I feel like saying something to her right now, I should say it."
*Uuuuh, hey, babe, wanna get laid?
Obviously, you don't come up to a hot girl on the street and ask her to have sex with you. If you want to do that, you're obviously insane(or very confident). Instead, ask yourself not what you want to get(sex that is), but what you want to say when you come up to her. I highly doubt that you'll come up with "do you want to have sex?". I hope you're getting my point.
The right way to approach things is not to think about the future AT ALL, it is hard, but possible.
AT ALL, means AT ALL. Your D'oh means that you're trying to predict the future again.
I can see this as something most people are not going to want to carry around. Phone, keys, wallet and sunglasses are too much as it is.
Maybe they can integrate them into purses/man-satchels/bras/brossieres etc. along with wireless recharging and built-in antennas in the straps.
Give it a few years, cellphones in early 90 had brick-sized batteries and yet people still carried them around, now it is hard to find a phone that is not a miniature wi-fi enabled game console with a video camera that can also make phone calls.
