TI-Nspire [CAS] v2.0 comments

improvement over v1.7 is there any reason for the scratchpad screen to
be smaller than full-screen? The presumed effect of a pop-up window
is not really necessary on such a small screen, especially when the
window title clearly states it is the scratchpad; no possibility for
confusion. So, why waste any bit of screen area just for a useless
visual effect?
About the keyboard: I think the new keyboard is more steps forward
than back (and I'm planning on getting the new version just for that
reason alone). Even though some keys were eliminated or merged into
one key (like the SIN/COS/TAN keys), I think it's done in a very
thoughtful and efficient way. For example, pressing TRIG/ENTER gives
SINe, TRIG/TRIG/ENTER gives COSine, etc. Not too much of a hassle,
considering the most frequent use is for SIN and COS.
But I still don't get it why they did not make the keyboard QWERTY-
style (both new and old)? (Is that just so the X, Y, and Z keys end
up next to each other, or was there another, more serious, reason?)
For anyone used to a computer keyboard, any different arrangement only
slows things down. Even students who may not have learned QWERTY yet
(I doubt there are any for the ages this calc targets), sooner or
later, they will be forced to learn it anyway. So, what's the
rationale?
Turning the unit off and on does not take you back where you were. It
does so if you let it power down on its own. But why this difference
in behavior? It's only one keystroke to get back to home screen if I
want to, but it's possibly several keystrokes to get back to the same
screen and position within it I was at when I turned it off manually.
So, on average, the user saves keystrokes by powering on where s/he
left off. (If opinions are divided over this, they could make it an
option to keep everyone happy.)
Pointing over the Settings icon (left of X) shows the current angle
setting (RAD, DEG, GRAD). The angle could be made a separate icon
(left of the Settings icon) for quick selection of the next angle
mode. Changing the angle setting is a common operation for some
problems.
The CTRL-ENTER forces an approximation when in EXACT mode. By, why
not do the opposite in APPROX mode (ie., force an EXACT answer)?
(This is the same with previous versions, and for TI-89 (Titanium).
So, this one applies to all these models.)

It doesn't evaluate it.

change, that might be preferrable, and while I agree that the new
keyboard is a significant improvment and the scratch pad is useful, I
think the time is long over do for TI to make the nspire cas
mathematically competitive and more significant. When, if ever, are
we going to see the math capability that the competition has, e.g.,
slope fields, 3d graphing, etc., which is definitely significant for
undergrad college use, and can also be helpful for high school
calculus courses. These are major issues still to be addressed and
since actions, or in this case non-action, speaks louder than words, I
am wondering if perhaps TI simply is never going to make significant
math upgrades. Perhaps they don't have the talent to do so? In the
mean time, buying other devices is preferrable for college undergrad
work.

locations except in a question and answer template. This seems odd.

On a 'Question' page CTRL+M gives me a MathBos but it behaves like a 1.7 version and doesn't evaluate.

cold and am a bit foggy). Whey does it revert back to its old ways???

scratchpad while in a document, then you can't know which of the three
possible screens you were at (doc, scratchpad A, or scratchpad B.)
