Laptops with Trackballs?
txsable asks: "Is any manufacturer making a new-model laptop computer with a trackball? I can't stand touchpads, and the "accupoint" device used by IBM and other isn't much better. My favorite is a Dell Latitude XPi CD that belongs to my office, but (1) it's a Pentium 133 and (2) It's not mine!" I used to remember laptops that had those trackballs that attached to the side. They were alright, but their main drawback was that those things always broke, or at best, would fall off because the attachment didn't fit right. Are there any laptops out there that actually have the trackball integrated into the unit in a position that feels fairly natural, and also doesn't get in the way of typing?
Why not just get an external USB trackball? There are several really good ones. Hell, I even saw one the other day that ya wore on your index finger and manipulated with your thumb (believe the button was like a trigger as well...good for the gamers :). If ya could type with it, it would be even better than having it integrated anyways.
Anywho, I haven't seen one installed in any computer in years. The last one I had was an old Powerbook 140. Oops admitting that is enough to get my karma demoted to under 50.
BTW Heh! My First First Post! Womder if this will get through the crap filter...

Trackball and mice have moving parts and a touchpad or a pencil eraser-like thingies don't. This probably means that they're more likely prone to breaking or malfunctioning, and they're also likely to be more expensive to intergrate.
I'm not an expert but I'm willing to bet that since only part of a trackball's surface is exposed at any given time, the rest of it would have to take up valuable real-estate inside of the laptop, probably more than a touchpad would. That's why you almost always see them attached to the side.

I haven't seen a trackball on a laptop in years, although the side-car style that old TI and Toshiba laptops used was pretty nice.
If you can find one of the old sidecar style ones, or even a serial or USB trackball that is suitably sized to bolt onto the side of a notebook you could probably rig something up:
Most laptops have removable a floppy/cd drive bay, or PCMCIA slot or 2nd battery slot, usually one of these would be located on the "correct" side of the computer.
Whichever slot is free, find a plastic blank or construct one out of plastic/wood/whatever, then mount the trackball to that.
Not as elegant as having one purpose-built, but with a little craftsmanship and a bit of luck it would probably turn out looking just dandy.

How did you get it to do up and down, how did you avoid acidentally activating it when typing a "j", and what does double left mean?
I see even classic Slashdot is now pretty much unusable on dial up anymore.
I bought a Logitech Marble Mouse to play trackball games in MAME. I liked it so much I bought another and use them all day long on my desktop and laptop. The laptop one has a few dings in the ball, but I'm not sure if that's from travel damage or my toddler chewing on it. If it gets a little dirty and starts sticking or flaking out (about once every 2 weeks), I pop the ball out and wipe the bearings and sensor with my finger. I get a lot less wrist strain than I used to with a regular mouse. The worst part is that the movement can be a little coarse and unpredictable when you're trying to do things like precise brushwork in Photoshop or sniping with a railgun in Quake. That's because the pattern on the ball isn't completely uniform. In 99% of what I do, I don't notice it though. When I need precision, I've got a USB Wacom pad & mouse I use.
I love laptops with trackballs - unfortunately you can't find them anymore, for some dumbass reason. My current laptop (and favorite, despite it being old and slow) is my Zenith Z-NoteFlex - uses standard SoDIMM's, and it has a trackball - unfortunately it is only a 486 DX2/50...
Anyhow, I understand the reason they don't put in TBs anymore is because of dirt, which is a reasonable position for an all mechanical trackball. However, I don't see why they can't incorporate an optical trackball (kinda like that logitech device, that has the funky pattern on the trackball), and thus cleaning would be easy as popping the ball out, wiping it off, wiping off the sensor, and that's it! I bet I know why they don't do it, though...
I have no way of proving this, so it is my own speculation - but what are the chances that logitech's patent covers any kind of optical sensing trackball? Hmm...
