Your iPhone has a touchscreen with a software keyboard, which is even more complex, annoying, and and expensive than a keyboard with buttons.
hmmmm... So the device that has out sold any other electronic device in the history of the world mainly because of it's ease of use and ergonomics, is in your words "more complex, annoying, and expensive". Ok, keep believing that.
And your sample size (5) re Uniden usability is far too small to be statistically meaningful. I'd venture that Uniden's sales and return figures paint a far different picture,, or they would have discontinued scanners years ago.
Really? Why would Uniden care if we bought there product, put it in the closet and never used it. They sold there product, made there money and were very happy to do so, as were there stock holders. I assure you more people buy a Uniden scanner and use it for 1 week or 1 month or so, and then shelve it for the most part vs those like many on this site that delve deeply into it and use it regularly. I'd put money on it.
Also, your're generalizing your experience with the user interface of a discontinued 8-year-old scanner to current scanners, which work differently.
Ok, please list the make and model scanner sold today that can simply do a text search of programmed freq's/ TG's. I'd would buy it first thing in the am. That is the point of this thread, to find a modern day scanner, which I have yet been able to find on the market. I'd love to find one!!
The way I currently see it is, only two things have changed since my first scanner 30 years ago. More memory was added to store more freq's, and the addition of scanning trunked systems. That's it! My Bearcat 100xlt had 10 banks of 10 channels each for 100 channels. It essentially worked exactly the same with almost an identical display and keyboard as my 396xt 30 years later. In between I had a 200xlt. Add in a few letters for text on the display, some more memory, and the ability to scan trunked systems, and that's all the progress that has been made. That's really abysmal if you ask me for 30 years of technology advances.
