Most companies spend time anticipating and planning for disasters. But in a global economy, where opportunity and risk go hand-in-hand, other events can be as devastating to the unprepared as any hurricane.

The corporate landscape is dotted with potential landmines that can take a toll on businesses:

• Skyrocketing energy costs and environmental mandates are forcing cuts in energy consumption.
• Security audits can distract IT staff if the organization is not sufficiently prepared.
• E-discovery requests can hijack resources and negatively impact productivity.
• Loss of key personnel can be a setback if a company doesn’t have a succession plan in place.
• Lost storage media, like a stolen laptop, can lead to tarnished reputations and lowered revenues if removable media isn't encrypted and digital keys well-managed.

►Just for Laughs

In the not-so-distant past, the choice between a desktop and a laptop computer was simple: do you want portability, or not? There were a few other clear-cut differences, too. Desktop models offered more power and features and were less expensive, while laptops were portable, but also more costly, and less ergonomic.

While some of these differences remain, advances in technology make many of them insignificant. Laptop prices have fallen, and the machines now offer even more power and features. Desktop models are less bulky than they used to be, and with the proliferation of devices like USBs, portability of data is not such a big issue. So how do you choose?

Here are a few points to consider.

When it comes to e-mail, I'm a packrat. No, it is not true that I still have the first e-mail I ever received. But I probably have my first e-mail from the year 2000. In fact, I probably have all my e-mails from the year 2000. So of course, I have everything since then, too.

Why do I have all this stuff? I'm not sure, frankly. Maybe I was concerned that I would be sued over some imaginary transgression and would need an e-trail to prove my innocence. Or maybe I was vaguely concerned about some legal requirement to save this stuff.

I'm not the only one doing this. Some of you have thousands of e-mails, too. And you probably don't know why you're saving them, either. Maybe you're worried about going to jail over some stupid e-mail you can't find.

I'm hardly an expert in what e-mail documents and records to save. So I talked to Donald Skupsky, the president of Information Requirements Clearinghouse. He modestly describes himself as the world's leading expert in this area. I also talked with Charles Fine, a Phoenix attorney.

Here are some things to consider when you wonder whether or not to save e-mail, particularly in light of the federal Sarbanes-Oxley Act of 2002, which imposes more requirements on mostly public companies to preserve records. Obviously, if you still have questions, talk to a lawyer.
