In my humble opinion (I've only been in TC 1 month) what has shocked me most about TC is that we don't have a configuration wizard (as in any other linux distribution) to detect your hardware and install everything you need to have a time zone, a clock server (if you don't have a clock battery in your PC) or the ALSA or if you want the Xvesa or the Xorg, if you have Nvidia, printers, usb, etc.etc.
Well... this is another history.
