For testing purposes I multi boot 9 OS's, all but one with Trinity DE.
I've tested 3 or 4 nightly build CDs and a couple of regular Ubuntu builds,
as well as Exe 3.3 and 4.1 and a bunch of apt installs on other Debians
and Ubuntus. Have had about 15 different Trinity installations total. Even
buggier versions were fast, stable and reliable on ancient hardware.

This 3/22/2014 nightly is close to being a really good turn-key distro
straight out of the box. I only had two major problems that are easily solved:

[1] The gtk-qt-trinity theme engine still causes a serious Firefox crash.
     I normally just remove it because the feature isn't really necessary.
     It's more stable in Mint 15 installations which also have either Mate
     or Xfce.

[2] Pulseaudio was not installed. Sound initially worked without it but
     then failed. Installed pulseaudio and then ran 'alsa force-reload' and
     now sound + video seem to be reliable.

And two minor bugs:

[3] Control center menu should always be visible by default, but have
     recently become hidden by default.

[4] Odd mis-rendering of Synaptic and Transmission widgets under
     Trinity. None of the core functions are affected, just looks funny.
     Occurs with or without Mate or Xfce installed alongside Trinity.
