It isn't new, I wrote that in my original mail. I know that v.90 is not
ADSL, my point was, as I wrote in my original mail, and is still quoted
below, is that back when that was written we were hearnig exactly the same
complaints we are hearing today, as if supposedly, only in Israel we don't
get the high speed connection that everyone else is , supposedly, getting.
When that was written, that was considered "high speed" - nowadays, ADSL
is considered high speed. Different eras, different techonologies, same
complaints, same amount of realism.
