Summary: I had the Kobo Vox, then got a Nexus 7 for Christmas. When the Nexus 7 suddenly stopped working, I was sad I had sold the Vox I've only had my Kobo Arc for a few days, but so far I love it. In many ways it is very similar to the Nexus 7. One interesting addition is the Tapestry feature. It allows you to group apps & widgets in groups on Home Screen, then you can pin Web pages, photos, music,quotes to these tapestries.
Summary: Good, all purpose open reading tablet that did not strain eyes. I find the Arc to be work as well as the Kindle Paperwhite but with more flexibility and enhanced features. As with any that works well, the more you use it the more you want to. I also found the slightly longer screen to be an asset.
