Like Joey I hate fans in my machines. I am a long term ThinkPad user. My main machine is still a T420s (the s model is a bit lighter than the regular T420) however I would love something like the Yoga 3 Pro but with a ThinkPad design. The Core-M is fine for my local computing needs the only thing lacking from the Yoga 3 Pro is a TrackPoint as I can't stand touchpads.
My ideal machine would be something along the lines of - fanless Intel CPU, 14" 1080p or better IPS display, excellent backlit keyboard with TrackPoint, 12+ hour battery life for 60% screen brightness and wifi, 3+ USB ports, 512+GB fastest local storage possible (so PCIe x4/M.2 or something). I don't care for anything else although I would take an HDMI or DP out and Bluetooth if possible :)
