We started our number port to ooma today. Despite the big outage Monday (which we didn't even notice) and the smaller outage on Tuesday, I still feel it is going to be a wise move going Internet-only. We'll still have our cellphones as backup, but ooma's call quality and premier services convinced me it was time to try something different. By my calculation, it'll take nine months of "no AT&T" to make up for ooma ($199), a UPS ($34.97 after tax) and the first year of premier services ($99.99), but after that, we'll be spending about $100 a year for a service that was costing more than $400. Sweet!
