The days of being chained to a desktop computer are coming to an end, and nowhere is that more evident than with entrepreneurs. For those that need to stay in touch and even conduct business while on the go, tablets and smartphones are making it possible to work from the sidelines of a soccer game or during a lull in a conference. The Samsung Galaxy III smartphone takes center stage, but some entrepreneurs still use BlackBerrys or Nokias.

“Last year I made the switch from the iPhone to the Samsung Galaxy S III,” said Valeen Bhat, owner of Brooklyn, N.Y.-based art education company Private Picassos.”I really feel as though this switch was the best for my business, as I utilize Google Drive, Google Calendar and Gmail to manage most aspects of my company of a daily basis. While the iPhone does integrate with these products, having an Android phone has made this process seamless.”

Hardware, software and memory swayed Sam Lazarus, owner of Wichita, Kan.-based ServiceMaster by Best, to the Samsung Galaxy smartphone. “Upgradeable memory was huge factor. The phone came with a 32GB [chip], and I added a 64GB chip,” he said. The screen size was also larger, he said.

However, the Samsung Galaxy didn’t score points with everyone. Said Winter Park, Fla.-based attorney Shane Fischer, “For months, everybody told me to get rid of my two-year-old Nokia smartphone, with its QWERTY keyboard and small screen, and upgrade to a Samsung Galaxy III. I did — for one day — and went back to the old Nokia because I knew how to use it, the battery lasted all day, and it didn’t have all these bells and whistles I never wanted in the first place.”

Finally, some entrepreneurs will always view the BlackBerry as the smartphone of choice. The physical keyboard that allows for fast email responses is important, but so is the image of professionalism that the BlackBerry projects, according to Amy Zhang, CPA, Managing Member of San Francisco-based Affinity Fund Services LLC.

“Blackberry, especially a black one, is still considered the serious executive’s smartphone. Most people associate iPhones with trendy/fashionable and Android with geeky. I don’t want me or my business to be associated with either,” Zhang said. “I don’t need my business phone to have Angry Birds or Instagram. Sure, it will be nice to have those apps for down time, but most importantly as a business owner, I need my smartphone to do its job and do it very well: getting business!”
