1. I would argue that iOS devices are too technically computers. What are you suggesting a PocketPC can do that an iPad/iPhone cannot? Especially considering PPC is obsolete, I can find a lot more uses for iOS than PPC. You're suggesting the smartphone has not evolved since 1998? Either you haven't used an old BlackBerry or you haven't used a new iPhone. The smartphone has evolved in every regard from speed, power, internet functionality, camera/quality, compatibility and integration with the rest of the tech ecosystem, etc.
2. Again this is you impressing your way of life on others. Just because you don't leave where you live does not mean other people do not or should not. I would say there are far more car accidents in city driving than on the highway. Getting out and seeing the world might do you some good. You'll avoid the highway for fear of an accident when the recalled items on your vehicle could potentially produce a far greater harm.
3. It sounds like you don't NEED a GPS or a Car. Or a phone or computer for that matter. If you look around we live far beyond a "need" society. In the US, everybody, including you, lives far beyond what is needed to survive. Compare the human race to chimpanzees. And remember, when you're traveling beyond your house, wifi does not exist everywhere.
My company (a hospital) gives me an iPad. Why? Because I am a clinical pharmacist which means I walk around from patient to patient optimizing their drug therapy. There are hundreds of thousands of drugs and an unlimited number of considerations you must make when prescribing and administering medication. One small error can lead to instant death and believe me it happens. Even with technology there are so many variables than cannot be accounted for. On a regular basis I use about 15 or so books alone that combined would be a few feet thick if they weren't digital. It's impractical to carry 15 books around. There are also many software programs used within the hospital accessible through the iPad. I could use them off a laptop, but a laptop doesn't have the same level or portability or battery life as an iPad.
There isn't always room either for me to set down a computer, plug it in, and do it that way. I suppose they could give me a tablet PC, but something like a ThinkPad tablet costs $2000+ versus $500. Multiply this by many other employees in different fields in the hospital, and the fact that the companies that make the software build it for iPad use, and there you have my answer.
I also have a laptop in my office for fulfilling other needs- projects, other specific software use, statistical analysis, research in certain online databases, etc. Again, it's not an either or situation. I use both my laptop, a Thinkpad T-series, and the iPad together in my work. Each serves a specific purpose.
They also give me a pager too! How do you feel about pagers?
Fyi: Print version of one of the top references I use- it's about 4" thick (and becomes outdated every week).
