The particular model I have is the QHD - 128GB version. It has a 2560x1440 touchscreen, 8GB of RAM, and a 128GB SSD.
Stock SSD is not terrible but could be much faster. Fortunately the RBS supports M.2 2280 PCIe SSDs. The Samsung 950 Pro 512GB version screams in this laptop, and can achieve sequential write speeds of around 1.3 GB/sec.
USB performance is quite good, 160MB/sec from USB 3.0 SDR devices.
The RBS can only charge from USB-C. It has only one port, so you can't use a USB-C device while charging unless that device also supports USB-PD and can provide 45W of power. The vast majority of USB-C chargers do not work, but the Innergie PowerGear USB-C 45 45W Laptop Adapter works. $37 from Amazon as of Sept 2016.
The RBS keyboard is unique in offering individual RGB backlighting on each key. It is intended to be controlled with the Razer Synapse app on Windows, but I've added support for it to this open-source Razer peripheral driver, so the LED colors can be controlled from userspace on Linux. You can also turn on/off the Razer logo on the back of the lid.
Most stuff works out of the box on Ubuntu 16.04 LTS. The touchpad is absolutely abysmal, and has no palm rejection whatsoever.
