Retina MacBook

From the reviews I've read, it is a great machine, and the display will make you drool.

From my personal experience of Mac OS X Lion, it's not that great in my opinion, it doesn't feel right. Earlier versions (Tiger, Snow Leopard) felt great to use. Lion is just a bit juddery. Hopefully Mountain Lion will fix these issues.

The guys at iFixIt are less impressed however - very difficult to repair, and terrible to recycle because of the glue and fused glass/aluminium. However in my experience Macs can last a very long time compared to a PC which surely should be factored into the equation.

Mountain Lion is a lot better than Lion, btw (in reference to my comment above).

Also, to be fair, Windows 7 is by far the best Windows so far, but I'd hate to have to use it for real work still.

You could save an assload, have upgradability, and still not have to deal with Windows by going the Hackintosh route, y'know.

Windows laptops with similar specs, design and battery life aren't that much cheaper though.

You may have the option of skimping out on CPU, GPU, RAM, Battery Lift, size, design, etc with a Windows laptop, but you may not wish to.
