I think that is why most people post "should I" threads. Realistically, my laptop alone can do everything I need or want. I was indeed looking for a few more hobby/fun machines. I was not expecting that a G5 could do everything I want to do, even for a long time. Just that today, it also happens to be able to do most of what I need/want to do.

One thing i have heard, and this may just be hearsay, is that apple is honoring an extended repair program for liquid cooled G5s to replace them with Mac pros, so if something did happen, that would be a nice perk. Of course, I am also not doing too badly at the moment, financially, so it would not be the biggest loss ever if I got what I paid for and a $250 G5 tower died at some point.

Also, good to know, re the latest flash player. A few flash heavy tabs can even bring my high end last-generation windows core2duo laptop to it's knees, in addition to the mid 2008 iMacs we have at my office.

Not being a suitable main computer is a risk we all take with hobby machines, and is a risk I would even be taking if I were to do something like get another sun ray client or switch my desktop to solaris instead of buying a Mac.

I guess the question I need to answer for myself is whether or not that g5 (or a new intel Mac, or a new workstation or gaming pc, just as examples) is more worthwhile than my other pet project idea, which is those thin clients.
