What do you thing, when does the time come to drop TLS 1.0? Looking at the ssllabs test it seems more and more browser than do 1.1, if not 1.2!
Well, trust me, XP and worse, IE on XP will be with us for some time to come yet. IE8 on XP will not handle 1.1 last I remember and IE8 isn't going to get any updates. However, come November when I have to get new certs, I think I'm going to toss 1.0 ... and tough luck for whoever it leaves behind. Firefox finally does 1.1 as of a couple versions ago.
