Cons: Waist of time, software is fast to install if you have everything installed already (.Net framework and other plugins) like me (but i'm a developer). After installation the software launches and i got stuck at login because it refused to accept my Windows Live ID, Windows Live Messenger works with it, but this one don't. So waist of time, and now uninstall everything.
Another thing, as always the setup created that stupid folder with letters and numbers that usually is not needed anymore after installation, but windows refuses to let us, to delete it.
Other Thoughts: To the guy (or woman) that wrote the description, i'm Portuguese and i probably have errors somewhere around my text, but what he or she wrote is nonsense. Commas were invented to do something...
