OTOH, touchpads and pointing sticks on laptops don't have scroll wheels.
All laptops with touchpads I've seen offer one or more of the following:
- scrollwheel emulation by dragging at the edge of touchpad (some touchpads
even have a slightly separated area for this, although this is completely
a software [driver] setting)
Yes, my laptop does have that too, and it's very practical for scrolling
in large documents. But I don't think it emits WM_MOUSEWHEEL messages in
Windows or the equivalent in X, since it only works in 'normal'
applications. It doesn't work, for example, for zooming in or out in
applications like Google Earth or similar.
If a Synaptics employee is reading this: maybe think about emiting
WM_MOUSEWHEEL messages in the driver instead of what the driver does now?
My laptop also has a 4-way button for scrolling horizontally and
vertically, but with the same limitation.
- button with up/down keys, which emulates wheel
- button, which you hold and drag on the touchpad to emulate wheel
Ah, that sounds nice. I'm going to pay attention to those things for the
next laptop I buy.
They often even don't feature middle mouse buttons, though I have never
understood exactly why. And IIRC nowadays more laptops are sold than
desktops.
I've yet to see a laptop with middle button, too.
If any laptop designer is reading this: I would very much prefer having
a middle mouse button. IMO that would be much more useful than all those
extra buttons for e-mail, browser etc.
Of course, people can just attach a proper mouse to their laptop if/when
they use it for serious graphical work. Which is a good idea anyway; a
touchpad is way too imprecise.
If your laptop has built-in blutooth adapter, I suggest you get a blutooth
mouse, this way you'll be able to use it without having to attach it to
anything.
Ah of course; I had been looking for a wireless mouse, but I was only
looking at the more traditional kind. Bluetooth would be more practical
indeed. My laptop doesn't have it built-in, but I already use a USB
Bluetooth adapter for other things. I don't know why I didn't think of
that before :)
Anyway, it's not that big a deal to me. Perhaps I shouldn't even have
posted my ramblings: things get blown out of proportion way too rapidly
on Internet (not that I'm accusing you of that, just speaking in general).
