EuroMIX: I'll admit I'm not looking forward to the day that I'll suffer from the same issue regarding Windows 7. It may still be some way away yet, but I know it'll come eventually.
Yup, I do not anticipate that day either, quite the opposite in fact. :) If memory serves correct Windows 7 is supported until 2020 on record currently. There's a chance Microsoft could extend that as they have in the past with some of their other operating systems though, but I wont hold my breath on it. I'm definitely not going to change to Windows 8.x when the time comes and don't know much about Windows 10 nor have any interest in it - probably like many XP users don't have any interest in Windows 7+ right now. I was one of them and used XP up until about a month before Microsoft killed it. Having said that, I didn't fight the change at that point I embraced it as there was no other viable option, and it took me about a week to get 99% used to Windows 7 and be more or less happy with the end results ever since despite my pre-misgivings.
But, when the time comes in 2020 or whenever it is that it's time to say goodbye to Windows 7 because it goes end-of-life and thrown to the dogs of insecurity, I'll be moving on to something else... Being a Linux gearhead for 21 years now, hopefully I'll be able to get the same level of experience out of the current Linux desktop offerings at the time as I get out of Windows right now. Only reason I don't do it already is despite my love and usage of Linux when it comes to gaming Windows 7 gives me an experience that is superior for what I am expecting so I continue to use it while remaining hopeful the tides will change, and hopefully thanks to Steam/SteamOS/SteamMachines, GOG.com, and to the plethora of game developers out there now supporting Linux - the next upgrade for gaming in 5 years will be to a full on Linux setup. Crazy talk yes, but one can dream. :)
DracoMagister: If some people can't upgrade their system because of legacy hardware, I suggest them switching to Linux* which can run on legacy hardware far better than any Microsoft's OS. You can still run the vast majority of the games here without any problem via DOSBox, SCUMMVM and WINE.
*Linux Mint 13 (Maya) it's a good option for that
In addition to some of the thoughts I expressed above, I would have to agree with some of what you're saying here now which is that IMHO it is a more safe and secure thing to do to install a modern Linux distribution that is aimed towards gaming or at least gaming friendly and do as you suggest than to continue to run an obsolete insecure OS. It will not do everything that someone wants and it will have a learning curve, but can be rewarding and worth it in the end potentially if one has the time and enthusiasm to give it a shot and doesn't expect everything to be 1 or 2 mouse clicks. If I had not put together my new PC for Windows gaming in Feb 2013 I would almost certainly be running my main box on Linux at the moment even though it isn't my chosen platform for gaming. Reason being that I put security above all else so running obsolete OS is not something I'm personally willing to do. Linux is a winner in that situation in my eyes, although it may not be for everyone quite yet - but I do think it will get there and it is certainly worth getting familiar with if someone hasn't done so.
