Apple loves Samsung as it's its number one supplier. We should all hope that finally the MBA is really challenged. Competition will bring much better MBAs to us, as Apple does respond to competition even though it has OS X to rely on.
I want Samsung's new line of notebooks to challenge MacBooks at all levels, and once the price matches the competition can begin. I would love to see Samsung challenge with high resolution retina-like displays in notebooks, lightweight materials and thin form factors, cutting edge technologies, and finally compatibility between devices and services.
I don't get all of the ridiculous trash talk against Samsung, as this isn't grade school and neither Samsung nor Apple benefits from the name calling. Competition WILL drive better Macs, and every time Samsung wins a small battle Apple will take notice. Whether it's a 400-nit bright display, a cool forward thinking design, or even just USB 3.0 making its way into the competition it will drive Apple to improve the MBA where it needs to.
I hope Apple rethinks the backlit keyboard, goes ahead with USB 3.0, adopts even better LCDs, and even goes with duralumin or some similar black design. The MBA is great, but IT CAN BE BETTER! And competition can twist Apple's hand faster than we can!
