I just took a look at the Asus W3j today (I'm in Taiwan right now, and happened to stumble upon a HUGE computer store with virtaully all the Asus models on display and for ppl to mess around with!) Naturally, I took a run with the W3j, and I have to say it is SEXXXXXXY!! Almost hotter than my girlfriend, but just not quite lol.
But in all seriousness, the W3j is a true beauty. It is sleek, stylish, powerful, and the brushed metal lid simply blew me away. It is by no means heavy, and its size is very managable. I wouldn't go for the A8jm, since it just has a few more USB ports, the built in webcam (which isn't that good anyway), and...I believe that's it? And oh, more plastic parts, and a plastic cover lol. SO, for me, its W3j ftw!
And the hot-swapple modular bay battery is another big plus.
