Why are you leaving Windows in the first place to come over to Mac only to have Windows again ? I thought the whole argument or reason to come to Mac, well for me it was because of build quality of the MacBook Air, and I don't like the direction Windows is going with their next OS release.
You will never fully grasp or appreciate Mac's uniqueness switching back and forth until you become comfortable with the Mac OS. This is why some find the adjustment so hard. You have to totally immerse yourself in the Mac way of doing things, then once you feel confident and comfortable enough then you can play musical chairs.
Anyway, you should be just fine.
By the way I had a dv-6 myself, but it was running AMD's quad core A-8 it was the Pavilion entertainment series. Nice laptop for $524.00 dollars on sale, don't know what the USD would be. And I loved Windows 7. Great OS. But I've had a burning desire to come on over to a Mac. Mainly for me as I said for the build quality. But I will always praise Bill Gates for his humanity work. Can't say much about the charitable Buddhist Steve Jobs.
But there is no going back for me. I'm now a Mac convert, and rather happy about it.
No one can build a laptop like Apple. And laptops are here to stay. And this Mac OS Lion is not bad either, and I figured it out in less then 72 hrs. And I get a free update to Mountain Lion later this month.
