Mostly touchpads, but there are a lot of differences that matter
between touchpads.
[The following long discussion might only interest me.]
The answer depends on the way I'm using the device.
Oh, and what I think I will do (when selecting a device) doesn't
always match what I actually do. That's why I've experimented with so
many things.
All trackpointers are the same to me (usable but not great).
Touchscreens are of no use to me with a normal Linux desktop.
Trackpads very wildly in usability.
I like mice best, but the logistics are annoying with laptops. Still,
if my session is longer than, say, a minute, it is probably worth
deploying.
For web surfing on an Adroid or iOS tablet, I quite like touchscreens.
Except while entering text. But I've never found that touchscreens on
notebooks useful:
- partly due to the crappy support in Linux desktops
- partly because what I'm doing often involves typing
- partly because horizontally reaching for a touchscreen is very
tiring ("gorilla arm")
- perhaps because Linux tasks require precision that is beyond
capacitive digitizers.
I rarely remember that I'm even on a touchscreen when I'm using one
with Linux. (My main notebook, a Yoga 2 Pro, has a touchscreen. So
does our kitchen computer.)
Trackpointers are simple in concept but I've not really gotten used to
them because I don't have one on my desktop where I do most of my
typing. (Or on the typewriter or keypunch where my muscles learned to
type.) My main notebook for five years (x61t) has one and no
trackpad, but I carried a mouse. The trackpad should be good for
touch-typists (it's in the home row). But on my high-resolutions
screens, it takes a long time to move a significant portion of the
screen. I've always found it a bit, well, creepy that the cursor
often drifts when I let go.
Touchpads on notebooks have a variety of designs with a variety of
good and bad points.
- I hate it when touchpads decide that I'm talking to them when I
don't think I am. The cursor will zing off somewhere while I'm
typing or thinking about typing. It may be my fault, but it happens
much more frequently on some systems than others. There's a simple
fix some systems have: ignore touchpad events while the user is
typing. I suspect that isn't enough.
- I am annoyed at the way touchpad use seems to require two hands
sometimes: moving a finger on the surface while clicking or holding
a button (or two!), perhaps even while holding a modifier key.
- having the left button being the whole pad seems like a step forward
but on my samples, it is designed as a lever with the fulcrum at the
top so (a) the pressure varies, and (b) is theoretically infinite at
the top.
- I like the new gestures that have come in. But haven't seen a
manual. So I'm not really confident that I know them. The most
useful seems to be two-finger sliding for scrolling (but there seem
to be two opposite conventions about the direction).
- the middle mouse button is useful in X and Firefox. It is rare in
trackpads (except thinkpads). Simulating by using left+right click
isn't as reliable.
- new trackpads seem to have soft buttons. My fingers cannot "feel"
where they are. So I have to look down from the screen. On the
other hand, if I put some effort in I could configure a middle
button, I think.
I don't seem to use a stylus. My x61t tablet/notebook has a stylus
but cannot sense my fingers. I thought that would be worth trying,
but it hasn't been useful. If I were drawing things, it would be
wonderful: precise (unlike capacitive sensing of fingers) and pressure
sensitive. I am envious of Microsoft OneNote users, but in reality
handwriting is probably too slow.
I accepted a stylus in the Nokia tablets and the Sharp Zaurus. But
the iPad was a real revelation: a fluid interface and not cramped (10"
vs 4"). But I perform some tasks better on the earlier tablets (ssh).
(I actually do some things in busybox on my Nexus 4, but only because
I haven't bothered figured out how to create a GUI for these tasks.
These same tasks are probably better on my Zaurus but it is usually on
the shelf, uncharged.)
