> 1. I doubt you can accurately focus a field with touch at that screen size and finger size.
You actually can and it works fine, but I see your point here.
>2. Paging is horrid as there are no consistent semantics relating to persisting the changes.
This does have consistency that carries over from the 39 which is all changes are immediate. Granted, I personally prefer the confirmation style, but it is definitely consistent. That is also consistent with the behavior users are used to with smartphones where settings are selected and there tends to be no "ok, now apply all of this".
This devices uses the concept of view switching. A screen like this can be immediately left and changed to another view/application screen. There really isn't any sort of cancel or validation.
> The 50g suffers from this terribly, particularly if you hit MODE, change something, then do DISP soft menu.
Yeah, that really sucks. Never liked it.
> "reset these to defaults" soft menu item, particularly with touch on which it is very easy to mis-key and cock stuff up.
BKSP on any item does this, CLEAR on the screen resets all. Carries over from the 39.
>3. Having used the nSpire for about 2 years, one of the real pain points is that it tries to pull off a desktop user interface, badly. It is pretty much stated above that you are trying to achieve that.
Nah, I think you misunderstood there. What I was saying is that any type of list selection item pretty much looks the same and there are only so many ways to make one. There are definitely benefits to doing things in a way that are recognizable to users.
My biggest gripe with the nspire is, as you say, that it is just a desktop application packaged onto a small device. Really, really, really bad idea in practice.
Prime definitely does not follow that. However, the goal definitely was not to completely replace the UI and turn it into a smartphone. It had to still be recognizable as a graphing calculator. There is not any sort of "dragging on scrollbars with a cursor" or things like that such as on the nspire.
