All I can say is that as a consumer, you can't listen to all of the hype and dive in early unless you just want to, can afford it, and be willing to accept that a product doesn't live up to your expectations. Everyone's situation is different - between what they want a product for, what it does or doesn't do, and in this case (being a radio scanner), what what you want to listen to in your area. Clearly, even with the features actually available, users have had a wide variety of experiences - both good and bad. That's bound to happen.
Did Uniden advertise and not (yet) deliver on a feature? Absolutely.
Is there much we can do about it at this point if we already own one other than to wait? Not much except wait a little longer if they are saying they are still planning to deliver.
What we can do is be much more suspect and cautious in the future when promises are made ... wait in the wings and see if the promises hold true - and decide at a later date if you want to jump in or walk away. Or just walk away from Uniden entirely and don't look back. Those are really the only viable options.
If you want to be first to own one, one thing is certainly going to be true... you'll also be first to experience any dissatisfaction in the product if/when it doesn't live up to expectations.
I have both a 436 and 536 and of course other older radios from both GRE/Whistler as well as Uniden. All have something they do better than the other when it comes to features. None are "perfect" but I can't really expect that given the wide range of things they are trying to do to satisfy everyone.
As far as the back and forth in this thread - people should just be allowed to vent and not get into attacks on one another. Say your mind and allow others to do the same and let's put an end to the attack mode discussion... There's still alot out there (for now) that we can do with our radios while we wait....
