Is SharePoint 2010 enough stable for production use

This question may sound kinda weird but actually, I need to convince my mangement of the stability of the newest SharePoint 2010 Platform.

What I would like to know is:

• Is there anyone using SharePoint 2010 in a production environment
• Which kind of use of SharePoint environment (documents database, intranet, ...)
• How many users
• Your degree of hapiness (user experiences, bugs, problems with the environment)

Your answer will help me to convince my management to switch to MOSS 2010 instead of 2007.

Thanks,
