My Libra arrived an hour ago. I like it. Didn't have much time to play with it, but everything seemed tip-top. It's fast and responsive. No buggy touchscreen. The frontlight is not perfectly even, but quite ok, without any unusual hues. The warm light is orange when all the way up, not "virgin's piss"
The Libra is comfortable to hold and the black bezel doesn't attract fingerprints, like my Kindles do.
In short, I'm pleased with it. Will be playing with it in the evening, Calibre, custom fonts, patches, the whole shebang.
