iPhone works for this dumbo :-)
It's a GPS and phone in one, plus holds lots of applications, which are toys to get you what you want.
It will involve learning something new, BUT it is NOT learning technical computer stuff AT ALL, that is a misconception. It is simply pushing buttons, just as with a typewriter, that do different things, just like pushing A to get an A typed on a piece of paper.
You can use a typewriter, right? You push "A" and an A appears in type, right? It's the same with a smart phone, you press Home to unlock, and it unlocks. Then you push what you want: Camera, Messages, Gmail, Google, etc., forever :-)
It does take time to learn, but it is SO worth it, handy as all hell. It will get you places, just like a GPS, BUT it will route you the best and shortest way, AROUND accidents, etc.
And find the best restaurants, museums, whatever you want.
Dive in the pool and be prepared to ASK for help, from everyone, even strangers, it WILL work.
