I was battling between Vaio Pro 13, Macbook Air and VAIO Duo 13 (haswell). I was really close at getting Vaio Pro 13 for a very good student deal, but the build, trackpad and horrendous WiFi problems made me to go to Macbook Air. While I'm more of a PC and linux guy on desktop, macbooks trackpad and UI are near perfect for laptop use without touch screen. VAIO Duo 13 seemed really interesting. Price was just a bit too much for me. Also solid clamshell design was better for me when typing is my main use.
