The response of competing vendors is my favorite thing about the iPhone. Oh, the iPhone is a fine device, but a single great device rarely moves the market forward in a significant way. It's when the rest of the vendors have to respond to a great device that we see markets taking great strides forward. Those strides are beginning to be taken with the crop of handsets now being released. Nokia, Motorola, LG, Symbol, HPC, and others are busy getting products out to the market--products that build on the ideas behind the iPhone's revolutionary user interface. It's not all about pretty pictures and touch-screens, though; the newest phones have great functionality built in, too. Enterprise-ready mobile operating systems, highly-usable GPS modules, push to talk functionality--the world is changing for smartphone users, and the changes are going to make the mobile life even better. -Curtis [1]
