Hey all, I was wondering if anyone is using a single UPS for 2 computers - a Mac and a PC. Should I look for something powerful enough to sustain both computers and some peripherals for a decent amount of time, or get separate UPS's. I have a 24" iMac (ordered today) and my Windows XP box. I doubt there is a UPS that will communicate with both a PC and Mac at the same time, and I'd like for the unit to shut down the computers in the event of power failure. Thanks
