I really don't care about the aspect ratio change from 16:10->16:9*, what bothers me more is the prevalence of low resolutions masquerading as high resolutions: 1366x768 screens are everywhere, marketed as "HD ready!" so that consumers think they're getting a nice high-res screen, despite it probably being significantly lower than what they're upgrading from. :@
