1) IT WORKS! -- Unfortunately not a given - i.e. it does not crash, runs apps reliably, picks up signals, oes not break easily, etc.
2) Form Factor -- Size, display quality within size, etc.
3) Battery Life -- Goes to 1. If the battery is dead, it does not work.
In order of priority:
1) Size, meaning not too big, not too small. Must fit in front pants pocket.
2) Battery life
3) Performance -- fast processor and fast enough internet connection.
4) Weight...because it travels in your front pants pocket.
5) Ruggedness. Gorilla glass and a neoprene skin usually takes care of this.
6) Interoperability with other devices in my CE ecosystem -- share or display media between phone, tablet, TV and desktop PC.
7) Thinness. Sure, why not? This usually goes along with light weight anyway.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
