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
I used to have one, and in a pinch or in a hotel - yes totally worth it.
