I have put together some figures on visitors to the PerfectTablePlan home page by operating system over the last 6 months. For clarity I have left out Windows NT, Linux and some of the other OSs that don’t figure very prominently amongst visitors to this site. I think these figures show some clear trends. You will have to click on the graphs below to see them at a readable size.
The overwhelming dominance of Windows XP is clear for all to see.
If we remove XP from the graph we can see that Vista market share is rising steadily, by about 1% per month. There are also clear downward trends in Windows 2000 and 98. Windows 2000 users still outnumber Windows Vista users, but I doubt this will be the case for much longer.
Windows Vista has a long way to go to dominate the market. Personally I don’t see any compelling reason to upgrade to Vista, unless you are a developer supporting customers with Vista (even then you might be able to get away with running Vista inside a VM). Indeed there has been a certain amount of backlash against Vista. But make no mistake, Microsoft are the Borg. Relentless, merciless and unstoppable. Sooner or later your app will be destroyed or assimilated by Vista. If you haven’t thought seriously about supporting Vista you had better start soon.
Resistance is futile.
