I was going to say they should only be comparing them under the same driving areas, since I know they aren’t allowed in many areas.

But you’re right, it’s even tighter than that.

There are 2 types of “free”. Liberty, and price. “Free as in beer” means they mean the price version of the word. It’s a really old saying now.

Small size means a smaller battery. If they make the phone’s processor too powerful, the battery will run out in less than a day, and then everyone will be mad about that. There’s also less surface to dissipate heat.

Making things smaller is harder and more expensive, but people who want small phones don’t want to pay more than large phones.
