Ubuntu 13.10 installation report (german). bottom line: things work in general, Bluetooth is flaky (even under Windows), Ethernet (only available on OneLink dock anyway, rest of OneLink seems to work) does not work
Upcoming Debian 8 aka "testing" works pretty much out of the box. Installation is a little difficult without integrated hardwire ethernet and Debian not shipping non-free firmwares for the WiFi interface. After installation everything seems pretty stable. Linux Kernel 3.16 and up is recommended to get decent performance from the Intel 7260 WiFi.

Display "ghosting", according to Lenovo support forum most Thinkpad Yoga S1 manufactured before April or May 2014 can show more or less severe "ghosting", i.e. watermarking of the display image with contrasts or colors from a previously displayed image. This applies especially to LCD panels type "LGD LP125WF2-SPB1" with manufacturing date "2013 Week 0" (see BIOS hardware inventory)
Intel 7260 performance issues, some people report data rates as low as 200kbytes/s even in perfect reception scenarios. It seems to help to upgrade the IWL firmware to the lastest and use a recent Linux kernel 3.16 and above
Intel 7260 WiFi and Bluetooth coexistence, some people report that Bluetooth and WiFi almost block each other when high traffic is happening on one of them. No solution or workaround known yet.
MSI for Realtek cardreader does not seem to work, kernel driver fails to probe. Workaround: add option "msi_en=0" to rtsx_pci kernel module probe

According to Lenovo service the only user servicable part is the replacable digitizer stylus. Opening the case e.g. in order to replace the harddisk/SSD will thus void the warrenty.
