Yes some people do work tasks on a phone. There's a difference between that and using a phone like a PC. They aren't moving stuff around a file browser, installing ad-hoc apps, opening a command line, etc. They're still doing things the locked-down way, so the iPhone is fine for them, in fact younger people tend to prefer that.
