Hi Sam, Re: UPS -- Most of the weight of the UPS is a battery rather than a transformer. The battery is what allows power to flow to the computer for a few minutes in the event of a electrical grid failure. The only thing that you'll lose if the power goes out and you don't have a UPS on the line is whatever open files your are currently working on which you have not saved to disk. So if you are in the habit of frequently saving the work you have open, you won't be at much risk in the event of a power outage. Surge protection, which is generally included in the UPS circuitry is a very useful safeguard. Especially in areas that are prone to lightning strikes. I have a friend who was a National Park Service Ranger in Yosemite National Park who had the misfortune of losing several computer systems during lightning storms.
