Do you have MobileMe? I use iChat daily with friends and family that either use AIM (AOL Instant Messenger) or have a .mac/mobileme account.
You're probably using MSN as you're from the UK, but there's no video conversation with that. Sign up for AIM and start using iChat - it's good fun and a nice messenger.
Nope i use my phone for yahoo im, on 24/7 for family and close friends And i use aim on my xp sp3 box for everybody else and a growing amount of random tech support to friends and random people.
I use iChat regularly but I also have Adium for those times when I'm chatting with friends/colleagues who are not AIM users (usually scheduled chat sessions).
cant use ichat over here in australia, no1 uses the accounts that are available. everyone uses hotmail/msn/gmail. adium is great because i can be signed on with msn, gmail and bonjour (for talking to people when i am at home) all at the same time. love the program!
while ichat has really good features, its just not configurable enough and it doesnt offer enough things for me to switch to it.
I use iChat all the time. I just like the way it looks. If I have to talk on MSN, ICQ, Yahoo or the such, which is becoming less and less these days, I use adium. I tried adium over iChat, but that didn't last too long. Loving iChat, and will continue to use it.
Use iChat all the time for AIM and GMail. Adium's interface is pretty crap, and the feature list pretty poor (no video?!) and also is much slower. Plus, I don't use MSN so that's not an issue.
