IM invasion: top chat apps compared

Like e-mail, instant messaging has become a part of our lives, at work, at home, at school, on the go--even on our cell phones. We take a look at four top chat apps, all of them free, and weigh the relative merits of each.

Multitasking: these days, it's a necessary part of any job and of daily life. So the ability to have a phone conversation while sending several instant messages simultaneously can sometimes make or break a business deal--or your date for Friday night. Instant messaging is fast, convenient, and--dare we say--entertaining, whether you use it at work, at home, at school, on the go, or even on your cell phone.

We looked at four leading instant messenger (IM) apps: AOL AIM, ICQ, MSN Messenger, and Yahoo Messenger, our Editors' Choice. All are free, although AOL and MSN offer additional features for a price. All are primarily geared toward casual Internet use (AOL AIM offers several business-related features as add-ons) but work acceptably in an office environment as well. In our reviews, we examined these apps' strengths and weaknesses with regard to setup and interface, feature set, and customer service.

Unfortunately, none of these chat apps allows you to talk to friends registered with other services. In other words, your AIM account can't talk to you best friend's Yahoo account--that is, unless you use another piece of software, such as Trillian. Trillian breaks the chat app monopolies by supporting all four major IMs: AIM, ICQ, MSN, and Yahoo, aggregating your accounts on each into one interface.

If you're concerned about security risks with instant messaging, specifically about buffer-overflow attacks (a common means of penetrating PC defenses) and spim (IM spam), you could try IMsecure, a security product from the people who make the ZoneAlarm firewall. It's the only product of its kind, and it works with AIM, ICQ, MSN, and Yahoo chat apps.

AOL AIM 5.5
Despite several business-oriented add-ons, AIM 5.5 is a free and versatile instant messenger that's best suited for AOL home users. That said, we like Yahoo and ICQ even better.
Full review

ICQ 4.1
The free, legendary chat client just keeps getting better; ICQ is the best pick, along with Yahoo Messenger, for features and versatility.
Full review

MSN Messenger 6.2
Relentless offers for premium (fee-based) services turn MSN Messenger into a big advertisement rather than a useful communication tool. For the most free features, use Yahoo or ICQ instead.

Yahoo Messenger 6.0 Editors' Choice
The most versatile and best free IM client we reviewed, if you can do without e-mail tech support.
