Dell X1 based upon popular Samsung, but far less $: http://www1.us.dell.com/content/products/features.aspx/latit_x1?c=us&cs=04&l=en&s=bsd
A "Detachable Monitor" to me is a major breakthrough as it allows me to recreate the home trading environment on the road. Staring down at a laptop screen all day is not an ergonomic option for effective trading imo.
I have an Asus W2V and x-keys. It's well designed, 17" excellent screen, very fast, light and it works well. It came with all the bells and whistles too. I had been waiting for something XP compatible both as well designed and powerful as the Mac laptops and the Asus is it.
