Great safety upgrade:
It allows you to see when your battery is starting to swell and acid starts to bleed, before it catches on fire, so you can call 911 to send the Bomb Squad to remove the battery from your device.

Warning!! You really shouldn't use this on the NYC subways system. Everyone will think that it's a hidden bomb!!


That Li-ion battery looks a lot like some C4 explosives, and it only takes one old lady screaming "BOMB" to bring a whole train to a halt.
Then the NYPD will pull a "grab n' smash" on your 4S and arrest you.
Yeah, a C-4 that reads Li-ion and it's FCC approved.

And an idiot who will place the 'bomb' on his hear just to start talking to it.
Thinking about it... there are lots of people who will believe that it's a bomb, specially New Yorkers.
When panic takes over, reason disappears, and chaos reigns all over.

The poster is a satire of such racist attitudes.
A lot of people who work long hours, including software programmers could look like Pakistanis after a long night working.
There are all kinds of people in this world, but should only be separated into Good or Bad people, not by race, color, appearance or anything else.
The Oklahoma Bomber didn't look 'Pakistani' at all, and he was a very bad person, wasn't he?
There are lots of people from the middle-east who are good people, same goes for orientals, africans, etc.
I would try to assume the poster was just being sarcastic, with no intentionally bad hidden intentions.

I have one of them, and that thing is really cheap! I mean.. really.
The glass has no oleophobic coating, and btw I just have used it for a week and the glass is getting out of the frame.
Windex and Silicone may fix it for you. That's the price of the cheaper alternative.
