I kinda like the look of them and often feel myself wanting a second monitor if I'm working on my laptop.

(I've come to the conclusion if people think I'm working I won't look like as much of a massive dork)

Always had the feeling they'd be a bit crap though, like the hinges break or the monitor isn't too good or it's big and bulky and you can't really carry it

Ideally I'd like to find a single fold out side monitor that attaches to my laptop (big chunky ThinkPad) somehow and doesn't need its own power supply but that may be asking too much
