Chromebooks: Chromebook 11 vs. Acer C720

I'm in the market for a Chromebook, and I'm torn between a few options. I'm loving the build quality, screen size, and keyboard of the Chromebook 11, but I'm not a fan of the silicon or the battery that powers it. Another attractive option is the Acer C720, which has the power and longevity that I'm looking for, but it's cased in a run-of-the-mill body. I'm not a power user (don't do Netflix, minimal tabs open, nothing intensive), and I want to keep it small and portable (hence the 11 inch screen size).

Has anyone taken the plunge with either of these options? I'd love to hear your feedback on your purchase. And if you weren't happy with either of them, which others can you recommend?
