Summary: This Vivobook S500CA is the second Asus which I have owned. I purchased my other in 2010 and paid about the same amount of money for it. As with most things, the quality seems to be diminishing, specifically, the keyboard.
Summary: Lets just say this thing is coming apart. All was well when i first purchased this ultra book but through normal use the screws that hold the bottom on are breaking loose from the plastic due to opening and closing the lid.
Summary: The touch pad would get stuck in down position when clicked. This was an out of box defect. I sent the unit off to the asus repair center and they fixed it. It took about a week for the repair. Asus covered all costs as the unit was under warranty. Unit is currently working fine.
Touchscreen glitching - exchanging for replacement.

Summary: I only used it for 2 hours before touchscreen started glitching and registering touches both while the computer was being touched and when not touched at all - even several minutes after not being touched.
Summary: The specifications for the ASUS Ultrabook S500CA-DS51 are good. The problem I encountered was poor construction. The keyboard is warped and as a result the keys are displaced rendering the keyboard impossible to touch-type upon.
