Office 2011 (Mac) is out. There are two suites, "Home and Business" and "Home and Student." ("Home and Business" has "Outlook.") Microsoft offers each suite in a single license-single user pack and in multi-license packs.
Buyer beware! If you only need one license, you can buy it, but not at the Microsoft store online. The Microsoft website offers only multi-license (more $$) packages.
Wake-up, Microsoft. You nixxed "upgrade" pricing, so make the more affordable packages available at your online store also.
