My view of smart phones:

* The cost is relative to the tasks it performs. With mail, messaging, web access and tethering, I can get work done in most major cities and between.
* They have survived my attempts to kill them. I've owned two Palm OS and two iPhones, a 3GS and a 4S, all survived daily use.
* No problems with reading the screen and my 3GS still runs apps.
* Growing list of 4G coverage
