How would you change HP's Envy Sleekbook 6z?

HP's range of thin-and-light notebooks like the Sleekbook 6z were designed to undercut the Ultrabook with cheaper internals. However, when the base model retails for around $600 and a bone-fide Ultrabook isn't that much more expensive, was there any point to this device? When we reviewed it, we found that the performance was sluggish and there was a finicky touchpad that detracted from its comfortable keyboard and decent battery life.
