2. I've used Windows and macOS concurrently, and was always amazed at how bad the Windows experience was (though, yes, it has improved, and unfortunately, as alluded to by Gruber in his piece on the new MBP [1], Apple has paid too much attention to looks and not enough to functionality in the last half decade).
