I seriously wish it'd survived and been enhanced. Much AJAX in practice is used to replicate the effect of <frame>s, but slower, buggier, and with more battery drain.
I agree. My understanding was that it had 2 major problems. 1) you could load other sites or 3rd party content in a frame which caused confusion - browsers should not have allowed that. 2) search engines had problems with them - that's not my problem, they should have gotten smarter. May have been helped by eliminating the first problem.
