From the moment I saw Apple's new shiny icons at WWDC, I started wondering if they would start making their laptops with a similar circularly brushed aluminium finish.
Apple are usually very consistent across their design decisions. The iPhone 4 and current Nanos and Shuffles already have round buttons that look just like that.
I think it looks pretty good, but if it's done on a large surface such as the whole laptop lid it would need to be a subtle brushing, too much glare would just look tacky.
I'd have to see this ASUS laptop in person to judge if it looks good. From the actual pictures in OP's link (not the renders), it looks way too reflective IMO, but then again it's not under conventional lighting, you can see a powerful spotlight is lighting the (otherwise dark) stage.
Also, if Apple ever makes Liquidmetal laptops, I wouldn't see them adopting a finish that could be mistaken for the current anodized aluminium. It would have to stand out, then they would make it a strong selling point and call it magical and stuff.
