Welcome to the M200!
I've had mine since Christmas, which makes me one of the old timers.
My machine has been fine overall. Your comment about the screen not being flush has been observed and is the case with mine as well.
How has my machine held up? Well, the hard drive crashed. It wasn't good, but I had it fixed same day under warranty repair. Other than this, I have lost one of my rubber feet from the bottom of the base unit and I have a very small and virtually unnoticeable nick in the screen in the lower right hand corner (near the clock in laptop mode). I also have a scratch on the outside silver casing, which was my bad when I turned the unit over to upgrade my memory.
Other than that (and the HDD crash notwithstanding), I plan to use this thing till it drops and believe it will last.
