variety makes world wonderful

when I trialed win7 7000 beta version months ago, I felt there hadn't enough inovative changes comparing to winxp or vista, but today after installing and trialing win7 RC 7100, I finally felt prety good. many features are in place and I can notice the intense competition between windows and linux, I haven't trialed OS of Apple before, so I have no right to say windows7 is also competing with Apple intensely, I can feel that windows had learnt lessons from the failure of Vista and got lots of ideas from Mozilla,from Linux and other competitors. windows7 accumulates many innovations which have been achieved in IT field from year of 2001 through 2009. Basically I think Microsoft have done a excellent job and I believe in the future there should not have monoply as OS is concerned, consumer have freedom and liberty to choose what they want basing on their specific appetites. meanwhile, we should not contiue to contempt windows or IE browser if they have been successfully impoved.
