- A quickie review of the new keyboard. These are of course my opinion.
-
- The mouse and keyboard are in all respects better than the previous keyboard.
-
- The mouse is very nice (though a little small for the largest hands). It is
- light and responsive. Twice (?) as sensitive as the old mouse. A little
- mousing goes a long way with the new mouse. The two buttons are great ---
- since they click in a very short distance and have great positive tactile
- feedback. They can also be pushed from anywhere on the button without strain.
- The mouse is seriously nice (unless you want an ADB trackball, I guess ;-).
-
- The keyboard is nice. I am already enjoying it better than the old one. The
- layout is far better, especially for programmers. Three major physical
- improvements have been made:
-
- 1. The 5 system keys (power, two volume and two brightness) have been
- recessed very nicely. The five keys have been changed to buttons which have
- short clicking distances, look very nice and won't be inadvertently clicked
- when reaching for the numeeric keypad.
-
- 2. Four characters ("|", "\", "`" and "~") have been moved to the main
- layout of the keyboard (from the numeric keypad). This layout change is a
- major boon for any programmers and UNIX shell users (since these keys are
- common shell and programming characters). Can you say "YAY!" ;-)
-
- 3. The command keys have been replaced with a recessed command bar below the
- space bar. This novel change is a major win. The command key will be much
- more fun to use now that you don't have to move your hand to reach a command
- key (rather, just thumb it with a thumb). The command bar is approximately the
- full length of the space bar, so it's easy to hit. However, there are two
- minor problems with it: 1. the feel of the bar is mushy, lacks positive
- tactile feedback (even compared to the rest of the keyboard), and 2.
- (hard/impossible to remedy) for long hands (like mine) one's thumbs collide.
- This problem doesn't occur with the space bar since typically just one thumb
- (ever) is used to press the space bar. However, the command key is
- functionally a shift-key (since it needs to be used in combination with other
- keys), so you want *both* thumbs to use it (and can't just let one thumb press
- it all the time). However, I expect this problem to go away with practice and
- time. The mush problem is not horrible, but I can imagine NeXT revising the
- keyboard to make the command key as responsive as the rest of the keys on the
- keyboard. Overall though, the command key is a clear win (regardless of these
- imperfections).
-
- The keyboard also has more tactile feedback than the old keyboard (and in my
- opinion is better than the old keyboard tactile-wise). However, despite the
- improvements, the feedback could be improved (I think). Perhaps, I am just
- used to my old IBM PC/AT (no flames, please :-) keyboard, and perhaps I've got
- tactile feedback ergonomics all backwards or something (so take the following
- with a grain of salt), but two features of the feedback irk me:
-
- 1. The tactile pressure threshold happens almost immediately when pressing
- the button, instead of steadily increasing and then releasing. I would rather
- have <Touch><Pressing><Pressing><Pressing><Feedback><Contact> instead of
- <Touch><Feedback><Pressing><Pressing><Pressing><Contact> (since the feedback is
- hard to distinguish from the contact with the button and is too (in my opinion)
- abrupt). The abruptness of the feedback seems to me to undermine some of the
- ergonomic value of tactile feedback.
-
- 2. The above problem is compounded by the following: the key press is only
- acknowledged at (near) the bottom of the key stroke. So, you *have* to keep
- pressing after the <Feedback> to complete the key press! This feature seems at
- least slightly counter-productive to having tactile feedback since (in my mind)
- the tactile feedback release should coincide with the actual key press contact.
- Neither of these problems are critical by any means, but I do find them
- irksome.
-
- Caveat: there may be some significant (to this discussion) keyboard ergonomics
- of which I am ignorant, so my above concerns may be hogwash (Have I mentioned
- that? :-). I doubt it though, since I *really* like the feel of my old IBM
- PC/AT (yes, I said it *again* --- are you annoyed yet :-) keyboard, and it
- exhibits the non-abrupt behavior which seems preferable to me.
-
- However, even acknowledging the above feedback foibles, the keyboard feels good
- and (in my opinion) is much better than the previous NeXT keyboard. And the
- mouse is awesome!
