I've just received what is probably one of the first few hundred X240 models to arrive in the US. First thing I did was rip out the hard drive and put in a Samsung SSD and install Peppermint Four:

By default, WiFi did not work at all. In fact the system would not even recognize that the wireless card was installed. Upon research, the Intel 7260 model cards are only supported in Linux kernel 3.11 and newer (Peppermint Four uses 3.8) so I grabbed the Ubuntu 13.10 kernel and headers and installed them and found some firmware to load and now everything appears to be working like a champ.
Performance wise, this is the fastest booting computer I've ever seen. No it's not the most outrageously spec'ed machine in the world but the boot process is mind-numbingly quick. In other news, the new ThinkPad touchpad is beyond terrible (at least I haven't gotten used to it) so I'll be dusting off the trusty Logitech M505 wireless mouse for a while. Other than that, smooth sailing thus far.
