First of all, i am not insane.(i think...)
Imagine that your football team wins the championship the last years and it has completely crashed all competition. Would you be happy with the way your team played with no competition at all? It would surely play crappy, because it wouldn't need to try any harder. Now imagine that your opponents got stronger by bringing talented players, accomplished coaches and investing in their infrastructure (academies, training grounds, etc). Your team would be hard pressed and improved to keep ahead of its opponents.
The same thing happened with windows.
Having more than 90% market share for years, they got slower, more bloated and less innovative.
Since the fall of Netscape, Internet Explorer stayed the same for 5 years. 5 years!! This amount of time is considered like an eon in IT. And then, with the advent of Firefox, Microsoft was forced to release IE 7, which incorporated some features of Firefox, like tabbed browsing for example. Now they even try to create publicity for the beta versions of IE 8, which in turn tries to catch up to Firefox in terms of speed.
Another great example is the end of XP lifecycle. Many users preferred XP over Vista and they even made an online petition to Microsoft to keep supporting XP. The result after 200.000 signatures? Microsoft insisted on terminating XP. But... But when EeePC came out, with this Celeron processor that could not load Vista, Microsoft was forced to extend the life of XP Home to avoid losing 100% market share to Linux netbooks.(And with this move it only lost 30-40%. I am talking only about netbooks here.)
Microsoft also finally implemented user rights on Vista, -badly though-, and started "discouraging" users to be administrators, when they shouldn't.
So even if you don't like or don't plan to use Linux, you should be happy if it keeps getting market share and attention from companies, because it is you that will be benefitted in the end. YOUR TEAM, Microsoft, will have to play better ball to stay on top and you will enjoy following that team more than you do now.
OK, you convinced me! How can i help windows, IE and office become better??
The easiest way is to add buttons or banners to download Ubuntu, Firefox or OpenOffice in your site or blog.
