Yes, I remember Windows 95.
It was easy to get the hang of, since I had already been using a Mac for years. (Of course, I had to break the habit of trying to use features that M$ didn't copy from A$$le...)
I installed the Win8 preview in a virtual machine, and I didn't care for it very much. But considering that I still customize my XP installs to classic, and Win7 installs to be as classic like as possible, I admit I am probably not the target consumer for M$. I use many different computers and I try to make my profiles on them as similar as possible. I am a creature of habit, and when I click the start button and see the "new XP" style start menu, I lose my train of thought. I put that puppy right back to classic!
Something I really liked with the classic Mac OS is that updates didn't remove features and functions, only added to them. I could integrate the new features and new shortcuts to make my computer more functional for me. They didn't just change the UI and say, "Use this! It's better!" (Well, now they do, but I don't buy A$$le anything any more. [cough] Galaxy Note running Android [cough])
My work computer is Windows7, and I like many of the UI features in 7, especially the windows snapping to the sides and top. I love that and use it constantly! I want to take the parts of the new UI and add them to the parts of the old UI I like, and have a custom UI that works for me. By eliminating the classic start menu in Win7, and eliminating the start menu completely in Win8, (and removing menus in Office,) M$ is annoying me to no end by taking my choices away and trying to make me do the same old thing in new and unfamiliar ways.
My computer! My choice! Do not dictate how I should set up my work environment. Give me all the options and let me decide what works best for me.
PS I would love to try a Surface or Windows Phone, but no one I know owns one, or has even seen one. Metro might work great on them, but at this rate, I will never know. M$ might as well be selling unicorns.
