Should you be running a UPS in your studio or office?

Today I installed a UPS in my office for the first time.  UPS stands for uninterpretable power supply and essentially it acts as a battery backup for your computer (or other electronics) should there be a power outage.  It had honestly never occurred to me that this is something you should think about, until something went very very wrong.  More on that in a bit…. but when I came to do a little research on the most popular UPS’ I was surprised as to how reasonably price they were. Why would you want to have one of these then ?
