Asus has loaded its netbooks with a custom UI for a few generations now, but the latest feels a bit more evolved. This next-gen UI sits atop the native operating system and can be called into action with just a click of a button. Chances are that the this generation will come on the T91 convertible notebook/tablet where the advanced GUI can really shine. It seems that Asus’s early entrance into this niche market is finally showing as this new Touch UI is extremely polished and might just be the most advance type of interface available.
