The biggest thing now is you have the entire civilization running windows 98, windows 2000, windows me, windows xp and vista. Microsoft and hardware/software developers will have a difficult time making anything to with millions using multple operating systems. Microsoft has a master plan to render 98/2000/me /xp useless. There is no more new xp being made for a long time now.They need to do this so they can use the operating system to be easily used with software/hardware. I think in 2 years 98/me/2000 and xp will be totally useless and we will be forced to go with vista or windows 7. The problem with vista is because of the complexity of hardware and software vista uses numerous libraries (files) and this makes computers not run efficiently. It is not as fast as anyone thought. Windows 7 is supposed to run differently.
I saw screen shots of windows 7 which looks a lot like vista. Microsoft should have made the entire look different so it would intrigue people and make them want to purchase it. Second, if they made it more affordable the mass population would migrate to windows 7 and make computer hardware/software designers and engineers jobs much easier.
All our bashing of microsoft is displeasure because we all run different os. It has to be a huge challenge to develop a new os and I pray aces high works on it . Right now I run xp 32 bit and I am capable of running 64 bit.
