So far I've only managed to get two monitors at work, but I've had multiple monitors since Windows 2000 supported them. Somebody had to support the three customers in the country who had them. At home I have a quad-computer/quad-monitor system, and I'm trying to figure out how to shoehorn two more monitors onto my desktop.
Then again, I had dual monitors on my old 8086 computer. If you knew how to do it, you could use a VGA monitor and a Hercules monitor at the same time, even under MSDOS. And, of course I did.
Getting extra screen for my laptop was on my wish list from a long time. Recently I got one with some Wally tactics. I don't actually use it as i find it difficult to work on two screens. But I guard this possession just for the status (*king*) as I am the only one with extra screen in my dept.
Also, I have placed this screen in a manner that most of my colleagues can't see me easily. (We don't have "cubicles" with walls :( ). This helped me in avoiding lots of help seekers and the like . I think this is the biggest benefit of the big screens.
Now with this little success i am motivated to keep up my efforts. I am hoping to get a cabin & and a secretary before i die.
*Yoric - never had the chance to rearrange keyborads, more's the pity, although did confuse my boss once simply by removing the ball from her mouse which kept the office giggling for an hour or two! This was back in the "old" days too, when that trick was still new.
In the meantime, I spent the first couple of years in my present job working on my desk expansion programme - pushing back the cubicle walls, being nice to the building caretaker to acquire additional furniture etc. Having reached a natural limit with that I am now in a phase of technological augmentation. So yes, two screens, mouse and trackerball (left & right, to reduce wrist RSI), laptop with remote wifi network access (so I can actually work from home), phone and a gooseberry (with which I can check my work email, plus facebook and my personal email accounts). And I've moved the department networked printer to be next to my desk. All in all not bad considering I was hired as a PA.
