How would you change MSI's X-Slim ultraportable line?

MSI's seductive X-Slim lineup first dropped jaws back at CeBIT, and it's been tempting PC addicts ever since hitting the market a few months back. Many have argued that the X-Slim family looks just a bit too much like that other ultraslim lappie over there, but we'd say these are distinct enough to walk their own path. Catering to a wide range of potential customers, MSI has actually issued quite a few of these machines, from the X320 to the X340 to the X600. If you've been fortunate enough to pick one of these up for yourself, how has the user experience been? Is it as much a looker in person as you thought it'd be? Are you satisfied with performance? Anything missing for the price? Go on and get heard, won't you?
