I was a little shocked (pun not intended) to see this article on LifeHacker. Doesn’t everybody know about Uninterruptible Power Supplies already? Then reality asserted itself, as I remembered that to most people, computers are just magic boxes.
When I was running a desktop system, the UPS was a must-have item. Now that I’ve only got a laptop, it’s a lot less important (because of the laptop’s internal battery), but I still insist on having one to run my other peripherals. GoddessJ’s desktop has one too, and we had to put one on my mother-in-law’s system as well, just because she was experiencing small brown-outs that were unnoticeable to the naked eye, but that would glitch her computer.
If you use a desktop system, I highly recommend a UPS. Even if it’s just a small one, it will let your system shut down properly before the power runs out, which will save you lots of time and headaches in the long run.
