If you’re one of those people who works outside of the office, and especially if you’re one of the many who loves that arrangement, your phone can be one of your best friends, or it can be a hindrance and annoyance. Buying the right phone can make a huge difference in your productivity level away from the office, and any of the following five phones makes a wise choice for those who keep long hours.

1. Blackberry Torch 9860

This all-touch smartphone from Research in Motion brings the touch screen to Blackberry in a very large way, with 3.7 inches complete with Liquid Graphics(TM). The Torch 9860 does everything you’d expect of a Blackberry device and more, with the new Blackberry browser and voice-activated universal search for finding what you’re looking for while you’re driving, walking or otherwise unable to type and look at the screen. The Torch 9860 also lets you separate your work and personal life on one device, which is a trademark of Blackberry business phone services and a real boon to those who work outside the office and also want to have said personal life.

2. Apple iPhone 4S

The iPhone 4S is well-known for the quality of its screen and the availability of apps from the Apple Store. iPhones are well-equipped for work tasks including email, messaging, reading and editing documents and, of course, making phone calls. What sets the iPhone 4S apart is Siri, a voice-activated search service which acts as your personal assistant.

3. Blackberry Bold 9930

If you like the Blackberry system, but you’re not interested in the full Torch touchscreen, the Bold 9930 might be just the device for you. With a touchscreen using Liquid Graphics (TM) and the traditional Blackberry keyboard, the Bold 9930 is the Blackberry you’re used to, but better. If you are looking for a smart phone that can handle voice calls, messaging, email, browsing and social media, you have found that phone in the Blackberry Bold 9930.

4. Motorola Droid Razr Maxx

For pure processing power, it’s hard to beat the Razr Maxx, with its dual processors, extra-long battery life and Super AMOLED display. With the improved battery life over the Droid Razr, this is a high-performance phone that can easily handle not only voice calls but documents, web browsing, messaging and email as well as social media apps.

5. Samsung Galaxy Nexus

The Galaxy Nexus is considered by many to be the best phone yet for the Android platform. With a Super AMOLED display which makes for crisp photos, videos and web browsing. The Nexus also features the latest Ice Cream Sandwich version of Android and is a powerhouse designed for people who need their phone to function as much more than a phone, including all the standard web browsing, email, messaging and handling documents and PDFs.

Any of these five phones would be a good choice for the road warrior or the living room warrior.
