I would also like to see Lifetime Premier offered again. I think many customers will never buy Premier because they hate monthly fees. These customers may be willing to cough up a couple hundred bucks to get Lifetime Premier and not have another monthly bill. I am one of those people.
Lifetime does not always mean lifetime, it's just a matter of phrasing. I cannot tell you how many times I have had lifetime memberships only to see them evaporate.
Just as an example...
If you have lifetime premier the service might change and be renamed to Premier Plus and your subscription will end.
If you don't believe me google around a bit and see how many times things like this have happened. Even Ooma cannot give something away for a true lifetime, eventually it will end as the services change.
My advise is to calculate the amount you are spending on lifetime and cost average it over 5-6 years. That is basically how long most so called lifetime memberships last. If that puts you in a winning situation then sign up. If you get a few more years then it is a sweet bonus.
Regarding lifetime membership, I think it's a sales tactic to increase revenue. Not assuming anything with Ooma, but I've seen a company go bankrupt a few years of offering the lifetime and was eventually sold to another company. As much as I like the lifetime membership, I'd prefer a monthly fee or perhaps a discount with annual fee.
