Thanks for posting this! For those who don't understand Russian.. The most interesting part of the video comes at around 11-minute mark, where the reviewer (Natasha) compares rMB performance to the latest Air. Basically, she says she was pleasantly surprised by rMB performance - Yosemite was "snappy", and the computer had no trouble doing all the tasks she did on Air.. which included light photo/video editing and playing Diablo. She notes that after playing for about an hour - the temperature of rMB body was 38 degrees (C), and CPU was at 60-65 degrees, and the rMB remained cooler to the touch than her Air doing the same task. She was able to get about 10 hour of battery doing web browsing. She concludes the review stating this was the best ultra-compact laptop she had ever used, and she's putting up her 11" Air for sale.
All in all - very encouraging.
