I've got a Libra Colour but you gotta keep in mind that colour trueness on epaper is not great. The notebook has limited colour choices and they all kind of look like pastel colours.
Besides that, I am not crazy about the refresh rate. It has techniques to refresh quicker than other ereaders, but it'll still be kind of spotty sometimes.
In reading, I've only seen colours on book covers and they look okay, but if has nowhere near the contrast or vividity of an LCD.
