Wanna try Linux without getting wet ? ( installing anything that is .. )

This is my second posting regarding the Knoppix Live Linux CD based on Debian GNU/Linux and I must say I was quite surprised with the idea of running Linux without installing or partitioning anything on my computer. As it turns out one of the main reasons behind the release of this CD is exactly the one mentioned above.
I never really planned on running Linux on my PC and after a quick session with Knoppix I am having some second thoughts. If I will buy a new machine in the future ( something that is bound to happen ) then my old one will turn into a Linux box for sure, if not a MythTV one.
I am quite glad that this alternative OS exists and even more glad that enthusiasts and great programmers keep on adding features to it.
On another note the European Software Patent directive should NOT PASS 'cause open source software is the best thing that happened to both Windows and Linux running machines, and if some cheap bastards over at moneycentral software county want to stop open source's chance of survival then they should rethink their future sales 'cause such a move would piss all the tech savvy ( the one's that influence the industry ) people off. Being a Windows user myself I find that more than 40% at work and 80% at home of the software I use is open source. If the European bill passes and extinguishes this kind of software then I would consider dropping out of the tech industry altogether, it would be as rotten as the entertainment industry has turned out to be, the executives not the performers that is.
Seems like the globalization that the activists are fighting against is all about decisions like this one gathered together to form a negative climate over our everyday lives like the one the major industries are trying to force down our throats ( calling people pirates with every chance they get).
Trying to get filthy rich is what drives this planet to doom. Damn, I'm totally off topic..
