I guess we need to define "biggest hit". Afterall, this is an internet forum and someone has to be right I still contend that Win95 will remain MS's biggest opening sales hit. I also think Barman58 is correct in calling XP the biggest hit interms of longevity and loyalty.
However, Win7 is by far the best OS they have put together. I think the UI is really looking good, I think that security is an absolute cornerstone to the architecture, and even in beta form, it's very stable.
