I'm also interested in a way to run KDE apps in Windows. I think right now the only way to do that is through the KDE on Cygwin project, but it only uses KDE 3.4.3, and a lot of fixes have been done in KDE 3.5.x
I'm particularly interested in just a few apps that I couldn't find any good equivalent in Windows, namely:
- Konqueror (I guess it's self explanatory)
- Kontact including Akregator (Thunderbird lacks an organizer feature)
- KOffice, especially KOffice Workspace (I only use OpenOffice to save documents in MS Word .doc format)
- KTorrent (one of the best bittorrent clients I've ever encountered)
- Amarok (simple but powerful)
- Superkaramba (Yahoo!Widgets and Google desktop just doesn't do it for me)
(Sometimes, I have to use Windows because of my sister, who I don't think would like Linux very much)
Btw, I just thought you might be interested to know that the Kubuntu 6.06 LTS Live CD includes some free software for Windows, which you can install by putting in the CD while you are in Windows. The interesting part is that it can install two KDE-PIM programs: Address Book and Calendar. I was wondering, if they were able to do have those two run on Windows, wouldn't it be possible to have the whole Kontact package run, too?
Here's the link to the Kubuntu page:
