Android vs. iPhone: Summary
If you've been keeping score, here's how things stand: iPhone came out ahead in the security and backup categories; Android won for storage, customization and personal assistant; hardware, apps and management were a tie. On a straight points basis, that would make Android the winner, but that doesn't really tell the whole story.
Different business users will have different priorities. If you work in the financial industry, perhaps security is such a big issue that you feel you need to go with an iPhone. Or perhaps you have a very fast-paced job where productivity is extremely important, making Android more attractive because of its customization capabilities and personal assistant.
Both mobile platforms offer features important to business users—it's a matter of your priorities. In your particular line of work, perhaps a category we haven't covered here, such as ruggedness or battery life, is more of a priority. In the end, it really is a personal decision, and you'll have to weigh the relative merits iPhone vs. Android for yourself.
