Well, I just downloaded it and played around with it. and I must say, It is the
best version of ICQ to date (and I've used every single one ever since 98a).
1. The download is like that of IE, allowing you to install only the features you want. My download was 3mb
2. The UI is
MUCH cleaner than 2000x and is more like that of 99a. All the crap has been cleaned and all the useless features are hidden.
3. Has advanced text functions (highlights, emoticons etc)
And most importantly:
4. it uploads your contact list to ICQ's servers and allows you to use your ICQ from any computer, including a Java ICQ version running as an applet.
Overall, it simply rules
oh, and BTW, my ICQ mem usage is 6mb, compared to the 12+ on icq2000.
