My boss has decided to put me in charge of selecting communication devices to step into the 21st century. The old nextel phones will be history. Smartphones are required for email, photos, etc. I have had 4 android phones over the years so I might be biased, but it sounds like that is the way to go. Boss says keep it cheep so I am hoping there are some decent phones for free (even my Nexus S 4g is free now at Best Buy). We have long ago earned free upgrades for all people. What do you recommend? Important is ease of use, durability, preferably a better camera than the Nexus S has. I phones are too costly so lets rule that out... Thanks in advance.
