It's bad. I have a ASUS MB16AHP (claiming a brightness of 220cd/㎡, contrast ratio 700:1) and yeah, in a brightly lit room viewing can be difficult. It's ok under normal office lighting but you'll be out of luck if you have sunlight flooding in. I've been searching for a brighter option but most (all?) the current offerings seem to be based on the same or similar internals. Still, it's a useful device while traveling – nice to be able to plop a decent multi-monitor setup out of a backpack. My model also has a micro HDMI port (and an internal battery) which can be handy if you need a temporary screen for a Raspberry Pi or a machine that usually runs headless.
