hehe you should; although it's still beta and probably has bugs it's much better than the previous.
some very nice characteristics:
It keeps track how long ago each contact you have was online from minutes to days.
icq history has a nice search function and it's not plain text like before, but categorised as calendar. (best one)
it has video/audio chat, which i havent used, but seems good idea.
