If you really want to experience OSX, you have to do it on Apple hardware and with Apple support. Walking into an Apple store with a laptop that is having a problem and walking out with a new one 15 minutes later is where they really shine. That's a much bigger deal than the OS for me these days. I'd wait for the next Macbook Air refresh which is coming soonish. Despite being far from the most expensive product in Apple's portfolio I feel like it's their flagship consumer computer.
