I accept this concept. But you could have used XP in VM instead because its the best way of testing out stuffs.
Some apps did fail to install in 7. Its a problem if you happen to use that exact ones.Yes I do know that almost most of the apps run well on Windows 7, but still its not 100%.
I never have to try it, because i have to USE it instead.Another thing as i said before, I hate the search function of Windows 7. May be none of you ever tried it.
Its much different from XP's. And i accept that its little tougher to use at first go. But you would feel pleased with you when you keep on using it.
