One highlight was being able to connect to it from my phone for the first time; first on my first smartphone (Symbian), then from my "non-smart" Sony Ericsson that succeeded it, via some Java Jabber client and a Jabber-to-ICQ bridge! (Unfortunately nobody else that I knew had it on their phones, so I could only reach people in front of their PCs at home.)
On the other hand, it is and always has been unencrypted (not counting the OTR OTT encryption layer I've been using on it with the few friends that were also on Pidgin or Adium :), didn't support offline messages or even being logged in on more than one client, and was entirely proprietary (not sure if it was part of the "chat wars" [1] too).
Ultimately, the only constant in life is change. Instant messaging is alive and well on other platforms and networks today, let's remember ICQ fondly and be happy that we have so many good alternatives :)
