Espruino-Boy?

If you're after nice black and white displays you could also look at the Sharp Memory LCDs. They are absolutely beautiful and amazingly low power, but unfortunately they're not exactly cheap either: espruino.com/MemoryLCD

Wow they are really sharp and nice.
I'm looking exactly for that kind of displays - don't need any colors.
The best would be OLED display of more than 2" like the small 0.96" once I used in my examples - but much bigger ;)
