Well, hopefully soon you will have a useful idea of whether it's viable - and if it is, a good guide on how best to achieve it.
Koroush Ghazi runs the TweakGuides site - one I've been using for info and whose guides I have purchased in the past 14 years or more(though he does free versions, too) and is a guy I trust about what's what in the realm of operating systems and gaming optimisation.
At the top here, is his latest post....http://www.tweakguides.com/
Hopefully, all will go well and we will have as good a guide as his past ones, on how best to make the switch.
I've made Linux O/S DVDs in the past, but never had all the info I need, or not been able to collate everything, to make an informed decision about whether it's a good idea to change, and then how to go about it in the best way. So I'm really pleased about this - and hope it goes well for Koroush, so he can help the rest of us.
If a decent competitor to Windows were to suddenly appear on the Market, I am convinced that MS would be in serious trouble - but that is highly unlikely, so the only remaining choice is to try and make the best of what is already available.
