I will second that the Kobo Libra Colour is an excellent device. To me it's the perfect reading device. To anyone using Calibre with it, make sure you get the Kobo plugin that transforms epub into kepub when sending to device. It normalises text size, margins, and so on so the reading experience is consistent no matter where you uh... procure your library from. I reconvert all my epubs anyway, but that step is critical.
