While the touch ID authentication for Safari auto-fill passwords is nice, it is incredibly annoying in clamshell/docked mode because every time I need to autofill a password, I'm prompted to type in my main computer account password. It's not really much of a timesaver and is encouraging me to swing back to using 1password as my primary password filler. At least with 1password there's an access timer so you don't have to continue typing in the master password.
