Are there browsers in use that don't support TLS? The most low-end browser (as in runs on the most low-end devices) I know of is opera mini and that supports TLS (since their servers do the actual fetching/rendering), looking at https://www.ssllabs.com/ssltest/analyze.html?d=lite.cnn.com&... CNN seems to support everything, including stuff like IE7 and android 2.
