A decade ago, few smartphones existed--some used PDAs for enterprise work, but they were far from elegant. Now, with 3G networks and Wi-Fi access making work on-the-go easier, Apple rules the space with their iPhones and iPads. Maybe in another decade Android will have made greater inroads, but there is no stopping the rush to develop mobile applications which enhance employees' productivity in imaginative ways.

Any MTR carriage will have plenty of folks glued to their iPhones, but iPads are a bit unwieldy in cramped spaces. Where the iPad shines is in executives' briefcases. We've held events where speakers ask us where they can plug in their iPad for their presentation. Senior tech executives read from iPads for their speeches, use them as a repository for their daily calendars and all the material they need for that day. As to whether an iPad will serve a laptop "replacement," there's a difference of opinion. But its value as an enterprise work-tool is seldom questioned--not by the busy, tech-savvy executives we routinely interact with who carry them everywhere.
