The short answer is yes. Unfortunately, if you viewed an innovation adoption curve for the industry, you'd probably resound "well...not until 2020."
Aside from the basic web-browsing and emails, firms and employees should take a hard look at how integrated technology on the smart phones today could help them work better and faster.
One of the neat features that Google's Nexus One is offering is voice-recognition for everything on the phone. Write emails, update social media, run apps, call people, find places--without touching the screen. (quick and cool video)
High-speed technology (1Ghz...that's faster than an iPhone) like this could be a life-saver for a high-level executive who might not be so quick on the mobile keyboard, or for the business developer who is on the road a lot, or for your field crew who might have their hands full or perhaps covered in mud!
But simple communication like the aforementioned is just the beginning. The shift that smartphones could bring to the industry could be very monumental. Talk about replacing your desktop CPU and desktop phone altogether. Instead of operating out of a bricks & mortar, you could have half your team cloud computing--and at the cost of a smart phone and service--you're talking saving your company thousands of bottom line dollars per employee.
