I read this thread before. I find it funny how a lot of these individuals complain that the interface gets in their way. I have two words for them "Classic View". If they must be so old fashioned, they can use that. For the rest of us who like to live in the 21st century, we'll take Aero.
I notice a lot of complaints mainly because Windows 7 is different and not exactly like XP. These are the people who will tell you "Well, Microsoft should develop something better, something that improves upon Windows XP." They will then follow it up by saying "it should look and feel and be like XP." Basically, the only thing that would suit them is if Microsoft kept releasing service packs for a now woefully outdated OS that's approaching the decade mark in age.
But back to the interface, again, I notice a lot of their completely unfounded complaints are based on the user interface, which makes them less productive. Maybe I'm missing something but I don't understand how the user interface in Windows 7 (which you can make look almost exactly like XP if you wish) is counter-productive. They must be drinking the hate-o-rade! A lot of people there say "We want productivity". I'm curious how they define that because again, 7 can look just like XP, 2000, even 98 if you wish. Personally, I was so happy when at my job they upgraded us from XP to 7. I started the initiative by insisting on an upgrade to Vista, which I was given. About three weeks later, we were all on 7 because XP was just far too outdated.
I remember one person who went absolutely insane when he was upgraded from 2000 to XP even with the classic interface, he complained that it was just too different. That's the kind of people these probably are, they saw changes and immediately rejected them and called it an overall bad OS because of these changes.
