So the routine way of updating/communicating to the D10/D100 series these days is to use a USB-to-Serial adapter, which then gets you a serial port to use with the products from any PC. We sell one for $20 that works fine, and most that you can find at your big box electronics stores work well too.
Unfortunately, the internal hardware of that product line doesn't natively support USB, and the cost to re-engineer just that part of the system is prohibitive. Then you end up saying "well, that's really a new product line, well, isn't it"?
And so basically, the D10/D100 series products will live on in their current form until they sunset someday, and we'll keep inventing new stuff for the price points and form factors that we think there is a business case for.
It's all trade-offs, and we try really hard to find the right balance.
(This isn't ANY sort of announcement or even hint about discontinuing any product, or any hint about what we have in the hopper. It's just a general thought about how we approach product developement)
