Likes:
Easy meeting setup - You can create a meeting from popular instant message and e-mail applications with just one click. This makes it easy to turn a phone or e-mail conversation into an interactive online meeting.
Dedicated application sharing - Rather than share your whole desktop you can choose a specific application to share. This prevents people from accidentally seeing files or other applications running in the background.
Share keyboard and mouse control with other users - You can let any meeting attendee take control of the meeting and present. This is ideal for product demonstrations.
Desktop recording and playback - GoToMeeting lets you record online meetings in just a few clicks. You can record everything that's happening on the screen and teleconference audio.
Support for multiple monitors - You can host the meeting from one monitor, while you work from another monitor.
Dislikes:
Some features are disabled for the Mac - GoToMeeting is one of the first providers in the online meeting category to offer Mac support, but some features have limited functionality. For example, you can't record meetings from a Mac. The other missing feature on the Mac is application level sharing. When you're presenting from a Mac you share your entire desktop. I expect this will change in a future release of the software.
No video conferencing -Video conferencing isn't available in most of the online meeting programs we've tested.
Bottom Line:
GoToMeeting offers quick and easy meetings and offers presenters all the features they need to conduct successful online meetings.
