I understand, at least from what other people tell me, that dual booting with multiple o/s's(including windows) is the most popular method of installing linux. What do you guys think, should we eliminate windows completely or still include it? I understand that it supports more games than linux, but i doubt thats what linux users look at the most.

It really depends what you want. There is no definative answer. If you want more than one OS installed then dual boot - if you just want one then dont.

If you use a Windows system and is going to try Linux, dual boot is recommended. This way, you will alway have windows if there is something that you don't know how to do with Linux. Also, if you use some crippled documents, like .doc, you will want to make sure that your Linux system is cappable of readding it before you get ride of Windows (the same applies to IE only web pages).
With time, Windos become useless (and your games dtart to run on Linux, if don't already). So, after you got used to Linux, you can decide by getting ride of Windows.

If you are going to install Linux on a enterprize machine, however, everything is different. You have to take a look on what sftware will be running, how trainning will be done and how expensive will be to maintain both systems (hint, linux is harder to establish, but much more easy to maintain), then you can make a decision.
