Gold [top level support] and Silver [same with caveats] support
Gold:
- Word 2000
- Excel 2000
- Powerpoint 2000
Silver:
- Outlook and Access 2000
- Internet Explorer 5.0, 5.5 (note: author uses 6.0 just fine)
- Photoshop 7.0, Lotus Notes R5, Visio 2000, Quicken 2000
- Office XP apps: word, excel, powerpoint
Many unsupported programs. Some work perfectly, others have issues.

Pros:
- Gnome, KDE, command line: immediate access to winword, excel, powerpnt
- No need for a Windows OS install or license (vmware, dual boot)
- Needs much less memory and disk space, performance is better
- Integration with your Linux desktop "natural"
- Included documentation (I haven't needed it so far)
- User Support: ticket system, very responsive staff, mailing lists.
- Despite "unsupported" status, many programs will just install and run.
Cons:
- Not a "true" windows environment (but most stuff works well)
- IE Java Virtual Machine problems in IE6 (for now; may work later)
- List of supported apps, while significant, is not huge
- You can make things freeze up (movies in powerpoint?)
- Not optimal for "power" windows users.
