To wardv, we should also compare it to the number of security fixes for Linux. The Red Hat Linux 8.0 errata now contains 16 security advisories. The major difference I see is not the number of fixes, but the ability to verify if holes exist or not. I use both Linux and Windows XP.
My favourite from the Windows XP install was the MS claim "Fastest Booting Windows ever". I've got VMware with several different Windows installations. The winner of the Windows booting race is DOS/Windows 3.1 :-)
I'm been feeling a bit burnt out after the ghostscript 8.0 release. I contributed a few bug fixes, new features and did platform testing for Windows and OS/2. I only work on this stuff part time and getting patches to the appropriate standard and through the review process often takes more time than I wish. Other things get put aside. I'm hoping that this Christmas break I'll be able to finish off my GhostPCL updates for Windows and gtk+ display, and then get GSview printing and PDF writing on Linux, and then do the MFC code for GSview. My rule for coding is to maximise the platform independent code, and minimise the MFC and gtk+ code.
