I am using Debian 5 still for various reasons
Its my favorite operating system for developing web sites
I do not even want to move up to 6 as Quanta is not working there yet.
Problem is that now google is telling me my browser (iceweasel 3.6) is incompatible to access my account especially with WC !
So I need to have an other PC on with Ubuntu just to do these things.
I find that a bit steep, even my bank works on it.
I forsee a bleak futur when we will have somebody telling us what OS to use with what browser, what search engin to use and where to store out data.
