Re: considering mac mini for office Have you used Microsoft Office for Macintosh? About the only similarity is the name. They are very different products.
The Macintosh platform is a great platform, however if you have a Windows domain, Windows 7 Professional/Enterprise/Ultimate are excellent platforms too.
What other software do you run?
Depending on the "cloud" (fog) could be a train wreck waiting to happen.
With that said, the mini is a good machine overall - just a laptop with no monitor stuffed into a small case. RAM is upgradable.
