[A83] Re: 83p os
I had this discussion with their head of app/etc development once.
But they never brought up third-party OS systems, but they develop what is
best for them, if it's all internal, without an ability to hook in external
stuff, then they use it. Apps are what they consider the extent of tying
into their system.
They originally fought user-programs because they just thought it would hurt
them/abuse them, but later they realize it was quite the opposite and gave
up trying to get rid of them. I'm sure half the stuff you think is against
you is just the developers having free-will to design how they want. Some
might be though, depends on the system.
But, they like to keep costs down I'm sure and redoing current systems to
help developers out of their scope isn't cost effective, but working on new
calculators is.
