I am writing this post on my cell phone, which contains a more powerful computer than the PC I owned ten years ago. Because of competition in the electronics marketplace, electonic devices are getting better all the time. Without this competition, cell phones would probably still be the size and weight of a heavy brick, if they existed at all.
My cell phone is a Motorola Droid with cellular service from Verizon. Why don’t I have an iPhone? Because I have a friend who has AT&T service and is always complaining about dropped calls and other issues. Also, I like having a phone with a user replaceable battery and an upgradable memory.
Is my particular choice right for everyone? No, but thanks to the free market we all have that choice.
