Being told my browser is too old is mildly irritating to me because it suggests I am lazy and should really try harder to keep up with the rest of responsible society. Being told my browser is too “modern” penalizes me for the fact that someone else has not kept up with technological advancements. Telling me it could be one or the other? Pretty much useless.
If I knew which scenario was causing the problem, I could take action – by either installing the latest version of IE, Safari, or Chrome or trying to access this particular site on my old desk machine which is still running Windows XP. I don’t really want to do either of those things, and now I might have to do both?
I think I’ll just look for someone else to buy stuff from.

Not to mention a typo “usingd” should be “using”
