I'm looking to purchase a battery backup for my Quicksilver G4. I only want to protect it, the monitor, and my DSL modem. Anyone have any experience with This Battery Backup? According to an article on MacWorld it is compatible with OS X, but I'd like to hear it from someone on here. Also, it says it will shut down all by itself. Is that a PC-only feature? I haven't seen any mention of Mac software.<br><br>If you have a suggestion for a better UPS (in the same price range) I'd love to hear about it. Thanks in advance.<br><br>
