Wrong-o: Office 2013 is specifically not compatible with Vista. Secondly, forcing (or encouraging) people to download the c**tf**king thing piecemeal rather than offering either media OR an EASILY ACCESSIBLE full download is an absolutely horrible idea. Especially for mobile devices where Internet access isn't always great.

Click-to-run is a giant step back -- basically the equivalent of "insert disk 4 to install this feature" in Office 95, except that the disk is on the Internet. I'd rather have a full install that takes 15 minutes to do, but is a known entity, as opposed to a quick install that may need Internet access the next day, after it's supposedly fully installed.

Fortunately, I use OpenOffice or similar on all of my computers. Thunderbird or Mail.app for e-mail. Generally Firefox or Chromium for browsing. The only MS products I regularly use at home are Windows itself, MS Remote Desktop for Mac, Visual Studio (unfortunately), and Access 2007, which I need to support certain databases.
