If you want a non-gimped version of Office, you're locked to Windows.
Gimped or not, it's available in some form for both platforms, iWork is not. Why even bring it up as an example of Microsoft's supposed "lock-in" tactics when Apple offers NO version of iWork for anything other than Mac?
If you want IE (*shudder*) you're locked to Windows.
They were happy to offer it for Mac between 1997 and 2003. They saw no point to continue after Apple had launched Safari. Since you're determined to make Microsoft look bad, you would also have complained if they
had continued to offer IE for Mac, and insisted that they were doing it to protect IE's world domination. A glass is half empty if you want it to be.
If you want to use Zune (*shudder*) you're locked to Windows.
If you want to use Windows Media Player with a mobile player, you're not locked to Zune, you can sync it with pretty much any device with a memory that identifies itself as a hard drive.
If you want to use iTunes with anything other than iPods, it's a no-go, and if someone tries to circumvent that (Palm Pre), Apple locks them out.
Project. Outlook. Visio. Windows. Windows. Windows.
And this concerns the vast majority who buy the basic Word/Excel/Powerpoint edition... how? The Office family of products is not locked to Windows and the enterprise users who need Project and Visio wouldn't use Mac anyway, so it's hardly a tactic to keep anyone away from Mac. If so, they wouldn't make any Mac version, period.
