Zeb:

I’ve used it several times (both as attendee and presenter). The sales guys can tell you the pros and cons of how fast they get leads, and the format they get them in – it’s probably the most important thing about the tool for them – I heard minor complaints about that stuff, but I think the plan we were on dictated some of that. For me, it was very useful. I could show a single app or my whole desktop. Lag can be an issue for users without a good internet connection (especially troublesome for presenters with bad connections. It does allow you to take polls and chat on the side during the conference. You can record the webinar/meeting, which is great for technical presentations.

I have not used any WebEx competitors (LiveMeeting, e.g.). I think WebEx is a great tool, and it would work very well for distance meetings, as long as all attendees have decent web connections (doesn’t have to be super-fast – we often had 4 guys all in one small office sharing a T1 line, and it didn’t lag much).
