The chassis of this computer is so flexible and weak that it causes endless problems!The mouse pad is activated from BENEATH the computer if I hold it a bit more on one side than the other.I've cracked the screen on this computer TWICE because the interior chassis provides no rigidity and the glass within the plastic-sandwich can't take that deformation.The keys have come off and had to be snapped back on.The mouse pad gets oddly stuck on one corner, as a separate issue from activating from underneath the computer.I love the functional components of this computer, it's fast and versatile, but the physical integrity is TERRIBLE! It's already cost me $350 in REPAIRS, and it's only because I of my ethic of not throwing things away that I haven't replaced it.
