I don't think you understand what fragmentation is. Windows is fragmented both at the software layer, with all the different versions of it: 2008 R2, 7, 2008, Vista, 2003, XP, 2000, Me, 98, NT4, etc. And it is fragmented at the hardware layer, with all the different hardware configurations it supports(ed): type and number of processors (64-bit, 32-bit, 16-bit), type of disk (diskless, SAS, SATA, IDE, SCSI), amount of RAM, number and resolution of each monitor, input devices (keyboard, trackpad, mouse, joystick), etc. The fact that many apps can run on XP proves my point: despite being an extremely fragmented platform, it is possible to write an app that is relatively portable on different Windows versions and PCs. |
