The apple remote uses ultraviolet light, doesn't it? If you point it at a webcam you can see it light up, but when you look at it you can't... So you can have someone use it to signal things for various reasons.. Shrug.

Says my 18 year old cousin, from his college dorm room.

Coat the inside of the dish with something highly reflective, they make a sticky-back mirror-surface film, find the focal length, and you can smelt your own iron!! Or what ever else people with large parabolic mirrors do.

Aren't all iPhone to iPhone calls made without using minutes anyways??? Why bother making sure both parties are running an app?

I don't particularly care if the world at large knows that Im "Headed to the Gym" or that Im 31 years old.. My 'private' information is harmless.. Sure you can see that I like to play kickball or that I recently took a cruise and had an awesome time.. I dont see how its dangerous for a company to sell my status updates or my interest in apple computers. Its not like Im tweeting my bank account number, or posting my passwords to my embarrassing adult dating site profile on my "wall"... Let them see and sell my info.. WHO CARES? You want to talk about damning personal info, open a yellow pages phone book... there are directions to your front door right in there.. heh.

So did they get rid of stop lights on their roads?

Did they drop the use of power point?

Have they stopped labeling hallways?

Do the teachers not write information on the white board?

Does anyone wear a name tag?

Have they gotten rid of laptops?

Do they not use worksheets?

Are other students not allowed to take notes in class?

Did they outlaw pens and pencils?

Hmmm.. I imagine that if I had 29 BILLION dollars burning a hole in my pocket, I might consider buying the single most talked about web trend in current times; if for nothing more than to make my parent company among the most talked about things in current times. Good business sense.

It's strange that you tell your friends when you're going #2.. I, for one, use it to set up where to be with my friends.. When to be at kickball.. And ask for favors, without having to text 20 people individually. It's actually quite useful, when it's used in a way that is useful.

It would, at the very least, make for a much better Tweet App on my iPhone....
