On my home PC, Office is only really installed for conveniences sake. You know, open that Word doc, bash up the odd spreadsheet or Access database. I don't work from home anymore and I'm the only user who is fairly technically literate. My email is gmail so I don't use Outlook.
Given the scenario above, I don't do anything particularly important Office, so I'm interested to hear if anyone here has tried out the Beta of Office 2010, and what they think of it.
It's not an OS limitation as far as I can tell, I have the buttons you're missing on my installs of Windows 7. They are all Windows 7 Ultimate version and I'm logged in as a Domain Admin on my home network.
