One thing this machine lacks is the most intriguing feature of the new ARM-based (and lower-power) Chromebook 11 from HP: charging via Micro-USB.
To hell with your freaky mutually-incompatible and non-standard ways to get 3amps over USB! Give me a 12V DC, positive-center barrel plug any day... Vastly more durable than MicroUSB junk, and far cheaper.
Car adapters cost $3, since they're just a cord... Wall adapters are also dirt-cheap, and I can use any of the dozen I have lying around... Everything from my Netbook, to my GbE switch, to my computer speakers, to my NiMH battery charger, to my portable fan, to my UPSes, to my old video game consoles, ALL run on 12V DC. They can all swap adapters, because there's no crazy non-standard resistor levels on other pins that make half of them incompatible with the other half... And unlike MicroUSB jacks with the tiny reed in the center, barrel plugs are practically bullet-proof, can be inserted easily in any orientation, etc.
I tolerate MicroUSB as a middle-of-the-road standard, that is better than a complete mis-mash of incompatible charging connectors, and varying voltages (3? 7.5? 9? WTF?), but only for small devices. Tablets should NEVER have started using it, and larger phones that can't fully charge with 5V should be jumping to 12V DC barrel-plugs ASAP, and getting everyone on a compatible, higher-power standard.
