Hows about the new SONY VAIO PRO 13?
"the lightest touchscreen ultrabook" ever made (1.06kg)
13" screen, Full HD (1080p), 1.8GHz Intel Haswell
Up to 8GB of RAM, 256GB of SSD (super-fast),
Carbon fibre body, only 18mm thick, USB 3.0 x2, HDMI (full sized), SD card,
Up to 8 Hour battery life, Backlight keyboard
Sharp front corners
Runs warm (says Laptop Mag)
Or hows about the TOSHIBA KIRABOOK with:
a 13inch 2560 x 1440 display
8GB of RAM, 256GB SSD, only 2.97 lbs (1.35Kg)
The trouble with both of them is that you cant fold/flip the screens back and use either of them like a tablet.
Personally I dont want more than 1080p on a 13in screen, but at least the manufacturers are starting to build high res laptops... FINALLY!
P.S. The Dell basically has my spec, but rumours of flaky touch pad & build quality are putting me off.
