I don't have a UPS but wish I had one (and the boss asked if I had one) when I had a power outtage to my own apartment while online and in a meeting on the phone (which is cordless) with the boss working on a project.
We had some lightning and stuff, and I think it knocked out my router. I have it plugged into the surge protector everything else is and no damage to the main computer, nor the DSL modem but the router slowly died. If I was sure it was really lightning I could have the surge protector manufacturer pay for it (it's got this thousands of dollars warranty if your equipment gets broke, etc. if connected to the protector).
I lost modems a couple times to lightning. In fact, one time one i had actually went POP! That was it. It was under warranty and believe it or not, I sent it out and got it fixed for free - and upgraded chips too!

I think I gave it away after I got a faster one.
We sometimes get lightning strikes a lot in the summer. I remember during the course of my life we had a couple microbursts. One when I was a kid still at my parents house (everything STAYED LIT for awhile when a strike came down very close, or at the house - everything started going haywire, powered on and off like poltergeists and then dead. 6 hours later, the VCR showed the CORRECT time despite no power and not having battery backup

My dad scared me saying lightning was in it keeping the clock powered. LOL!) Another microburst was when I was living here at my apartment a few years ago. At night I heard a constant rumbling coming up fast and constant lightening. I knew it was bad so I unplugged everything, sheilded my eyes (I have problems with strobes, etc.), and found a way to cover my ears and jumped every so often anyway. It was a BAD one, worse than the one the struck at my parent's house. I didn't lose anything, not even power in that burst, luckily and glad I unplugged my computer equipment and stuff!
Microbursts are havoc, believe me!
