In my opinion mouse is
more comfortable in use than touch screen. But there are a lot of minuses and
pluses of mouse and, of course, of touch screen.
Pros and Cons of
Computer Mouses:
Pros
Great for gaming
Very portable
Easy to carry around
Good for Internet
browsing
Some contain advanced
buttons
Scroll wheels are
usually a part of them
Easy to scroll
Cons
An extra thing to carry
around
Can be small (whereas
mouses are have more room to move)
Hard to clean
Can get sticky
An extra thing to buy
(if your computer already has a trackpad)
Takes up a USB/other
port
Touch screen Pros
Direct: Direct pointing
to objects, direct relationship between hand and cursor movement (distance,
speed and direction), because the hand is moving on the same surface that the
cursor is moving, manipulating objects on the screen is similar to manipulating
them in the manual world
Fast (but less precise
without pen)
Finger is usable, any
pen is usable (usually no cable needed).
No keyboard necessary
for applications that need menu selections only -> saves desk space
Touch screen Cons
Low precision (finger):
Imprecise positioning, the finger may be too large for accurate pointing with
small objects
Hand movements (if used
with keyboard): Requires that users move the hand away from the keyboard; a
stylus requires also hand movements to take up the pen.
Fatigue: Straining the
arm muscles under heavy use (especially if the screen is placed vertically).
Sitting/Standing
position: The user has to sit/stand close to the screen.
Dirt: The screen gets
dirty from finger prints.
Screen coverage: The
user's hand, the finger or the pen may obscure parts of the screen.
Activation: Usually
direct activation of the selected function, when the screen is touched; there
is no special "activation" button as with a light pen or a mouse
Here you can see pros
and cons of mouse and touch screen. Each prefers that him closer
and more comfortable. Somebody choose touch screen just because it is more
modern and expensive.
