It is certianly still not completely without problems
That being said, I personally think it's the best windows to come out yet.
It certainly beats vista and ME by leaps and bounds.
There are still problems, but you expect that with a nearly infinite number of system component combinations possible in PCs.
I still feel lost on a mac, but understand win 7 completely, so I'm not sure I see the relation. Though if you would like for your windows to behave more like a mac, here's a little app I put on my sister's pc for her since she's such a mac fan.
