While I am using trinity on multiple computers, I can't really
recommend to do so:
 - it has new introduced bugs that did not exist in kde3
 - responses to bug reports is very slow
 - some problems when installing kde4 apps next to trinity
 - duplicated kde config in home because when you copy .kde to .trinity
   a lot of pathes still link to .kde (e.g. mails)
 - updates only seldom
 - does not have all packages kde3 had in lenny (e.g. openoffice.org-kde missing)

Advantages however are:
 + a desktop nearly as kde3 was
 + all the kde3 features ;)
 + some new features
 + works on current distribution
 + easy to install (packages available)


Some trinity related bugs and how to fix them:

== openoffice integration ==

trinity somewhat messed up the startscripts so that openoffice does not
recognice that it is kde anymore. So when you klick on a mail address
not the url handler
 /usr/lib/openoffice/basis3.2/program/kde-open-url
but instead the generic
 /usr/lib/openoffice/basis3.2/program/open-url
is started which is not able to start kmail in kde.

So if you want to start kmail, the easiest way is to set the environment
variable MAILER, so e.g.
 .trinity/env/oo.sh
with the content
 export MAILER=kmail

With MAILER set, also the generic code is able to start kmail.

== ktorrent ==

If you want to run ktorrent from kde4 next to
trinity, you may get following error:
Fatal: !!!!!!! ERROR !!!!!!! - KHTML default stylesheet version mismatch. Aborting. Check your installation. File used was: /opt/trinity/share/apps/khtml/css/html4.css. Expected STYLE_VERSION 1

(2640)/: Communication problem with  "ktorrent" , it probably crashed.
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "
	(return code 255)

This problem can easily be fixed by adding following line to the file /opt/trinity/share/apps/khtml/css/html4.css:
