Though it's the iPhone integration that's likely to garner the most attention, the file sharing power of the Egnyte offering is worth a look for small and midsize businesses on cost considerations alone. According to Egnyte CEO Vineet Jain the average SMB user of Egnyte's service licenses 5 seats for a total annual cost of $900 per year. He compares that with basic server costs of $7,000 per year. Even if you cut his estimate in half, it's tempting to forgo a file server and move to the cloud.
The $15 per seat license is for power users only -- they get access to all features. There's no charge for users to access the basic sharing and collaboration features AND there's no charge for additional storage.
And because it's based on familiar interfaces -- if you know My Computer for PCs or Finder for Macs, you'll be right at home -- there's no steep learning curve for user adoption.
