Acer's premium Chromebook 13 and convertible Chromebook Spin 13 will come to North America in September at respective starting prices of $650 and $750.
These laptops feature a higher-quality aluminum chassis, a tall 3:2 ratio 2,256 x 1,504 screen (plus a Wacom stylus with the Spin) and start with a 2.2GHz Core i3 processor and 8GB of RAM. You you can also spring for more advanced Core i5 chips and up to 16GB of RAM in the top-of-the-line Chromebook Spin 13 ($950). The regular Chromebook 13 only ever ships with 32GB of flash onboard, while the Spin 13 starts with 64GB and includes 128GB in its highest-end configuration.
Acer will sell these machines to "commercial customers," so you're more likely to have one issued to you as an employee than anything.
