April 2013: How It Works
For our annual How It Works issue, we break down everything from the massive Falcon Heavy rocket to a tiny DNA sequencer that connects to a USB port. We also take a look at an ambitious plan for faster-than-light travel and dive into the billion-dollar science of dog food.
Plus the latest Legos, Cadillac's plug-in hybrid, a tractor built for the apocalypse, and more.

The only time I have accessed the battery on my pre-iPhone cell phones was either when I dropped it and the battery cover came off or when I had to remove it to find the reset button. I don't need a replaceable battery. I'd rather have a cover that didn't come off when I dropped my phone.
Regarding the lack of a video recoreder on the iphone, that statement isn't completely true. If you make the decision to unlock the iphone and put the intsaller software on, you can in fact put video recording software on the iphone. I understand it's not a standard feature, which would be great, but if you take the time to unlock the iphone you really can increase the usefullness of the phone. Although it would be nice if apple would just put what is needed on the iphone instead of coming back a year later and giving us ANOTHER iphone. Obviousley this isn't the case, so go for the installer software, it works, and works well.
