There were some noticeable problems with these laptops (in design). Customer complaints about really bad backlight leaking, bent keyboards (in the middle), and the USB slots do not align with the outside shell.
Hopefully ASUS tries to fix these issues for a second revision of this laptop. They are coming out with another line of ultrabooks with dedicated graphics minus the IPS screen (:-/). ASUS S Series (this month or next month will be the "official release")
