IT managers in big organizations will buy applications in bulk from the vendor or have software written expressly for them, rather than buying it from an online retail store. However, small businesses may find it useful to pick up a few productivity applications over the phone, he added.

"The smaller the enterprise, the more excited you should get," Entner said.
