Some reviews that flaws or problems with micro SD card support, long loading times the battery, creaking housing, poor performance, or the pre-installed Launcher I can not confirm. What is important is an immediate update of the firmware, which is available after the initial installation. OK preinstalled Launcher I do not use but have the NOVA Launcher installed. This can be in the configuration known little to be desired. (S. Attached photos) For my application (stream music and video in the home network, the Internet, send e-mail and receive, organizer, photo viewer, reading books on the Kindle app) is the yoga 2 perfectly. Streaming of HD TV programs from Panasonic HDD recorder with the associated app works without any lag. The speakers are ok. Ideal is the handling of the lateral housing thickening. This means that the tablet can very well hold in your hand and the integrated stand saves the purchase of a corresponding sleeve. Only criticism: The edges of the stand must be sharp-edged. I can recommend 2 YOGA.
