In Pictures: 10 old-school IT principles that still rule

These graybeard IT tenets still reign -- when applied in their modernized guise

2. Good information security starts with good physical security

We’ve always kept the hardware locked away, limiting data center access to a small number of employee badges and keeping automated logs of who enters and when. It’s just that now, not every locked room is our own.

For SMBs especially, there are alternatives, ranging from co-lo facilities to full cloud.

But don’t pocket all of the savings from not building out your own data center. Invest some of it in a low-latency, high-bandwidth network connection to your offsite provider. Even better: Apply another old-time principle -- never have just one of anything. Make that two connections, with points of presence on opposite sides of your building, so a back hoe can’t take your business down by digging a hole in an inopportune spot.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
