Ubuntu's open week sounds like a really good idea. I'm just surprised that it is done to get users away from openSUSE as Mark Shuttleworth announced on the opensuse mailing lists.
Mark, let me reiterate that the openSUSE community and the Ubuntu communities share the same goals. We might put different emphasis on some of them, so let me speak just about one where I see a different focus.
For us at SUSE it was always important - and still is - to not only have a great distribution but to work together with the community to bring open source and Linux forward for the benefit of all. I was responsible for the port of Linux to x86-64 (now AMD64 and Intel EM64T). This port included not only development effort especially in the Linux kernel, the GNU C Library, the GNU Compiler Collection and the GNU binutils but also porting of many applications that were not 64-bit clean. All the code was available in the public and went in the public repositories before we made the first distribution. You could even get the code before any chips were available. Without this foundation, a first distribution on x86-64 would have taken much longer for everybody.
There's further development work in different areas, like NetworkManager, XGL, evolution and beagle, where Novell and openSUSE developers are involved as part of the open source community to develop a foundation that every distribution, including Ubuntu, can use.
Together with Ubuntu's great marketing and our great engineering, we can change the world (Note: I do not want to exclude other great projects like Debian, Fedora and Mandriva). The Open Week targeted at Microsoft users and developers would be a great idea!
Mark, I'd like to invite you to discuss what possibilities we have to work together against the domination of Microsoft on the desktops and servers - instead of fighting against each other.
I would prefer to see more users switching from Windows to Linux than just Linux users switching distributions.
Daniel, I liked your balanced response.
UPDATE: Burgundavia, thanks for your apology and pointing out the satirical reply.
