OK, I see your point, but you do realize that sooner or later, XP WILL be left behind, right. I'm mean surely you don't expect XP to be supported forever?
Of course not. But it will be left behind sooner than it needs to be - it's a perfectly functional OS. However, that's a whole different discussion.
There will remain a large base of XP users for at least the next couple of years, despite MS pulling the plug and despite SD moving on, should they stop development for it. I'm not in begging mode here; I just think it would be a shame if they did so. Should that be the case, I'll be back when I ultimately get a new machine with W7 (or W8). There would be no point in renewing until then is all I'm saying.
