thesaint05 asks: "So I was sitting here at my job where and IM is a pretty integral part of communicating intra-office. However, I have 3 different clients installed, and each has a different user base. Within the office we have an SIP server and use Windows Messenger. The Google Talk client is for colleagues and friends on the cutting edge, and AIM is used by pretty much everybody else (including a bunch of clients). So, after holding 3 different conversations simultaneously on all 3 clients (Windows Messenger with a colleague, AIM with my girlfriend, and Google Talk with a friend at a different tech company) I got to wondering, what are the strengths and weaknesses of all of these clients? Which do you use and why? If you could combine features from all of the IM clients out there, what would they be?"
