I have the original Ooma hub (thank you, ScottC, for that recommendation so long ago!)
Just got an email from Ooma hinting at possible degradations in service to the original hub because they no longer support it and offering me the latest Telo hub for $79 and, they say, I can keep my tax-free, fee-free plan.
Is there any reason not to? Conversely, should I just stick with what I have until it dies? I actually only use Ooma these days with their Premier option so that I can go online and forward all Ooma inbound calls to my cell phone.
