I have yet to find a PC that won't run Linux well and support all the hardware * (Compaq are renouned for their use of propietry hardware). Support is constantly improving - Some distributions are better than others
There is in a very real sense an inherent requirement for mankind to continually reinvent the wheel - usually an improved version of a different size and shape to everybody elses. Unfortunately this means things never quite fit together and the waggon trundles along lumpily with one triangular wheel, one square wheel, and two round wheels rather than running smoothly as the maker intended
The point, of course, being that nothing fits together properly even in MS operating systems and certainly does not, in fact can not, in a poorly supported OS like Linux, regardless of how good the underlying code is. An example of this lack of compatability is the trade off with me using XP as opposed to W2K just to activate dual display. OK, I get dual display, but my network connections become essentially one way and buggy and it now takes an age to display network files. Of course, commercial implications and the very nature of capitalism dictate that this is so - we need to pay those who need to make a profit in this non Utopian world of ours
If I were to install Linux on the Sony VAIO I can assure you the video would not work correctly because there are no drivers available. But, more importantly, I would not be able to run any of my other essential programs on the laptop. Support may be constantly improving but the reality is that our computers need to work now, with software as well as hardware, and not at some time in the future
Having said that I can see why those who would use Linux would appreciate a Linux version of ZionWorx. Not sure I would have much need of it though
