I have been using TD as well for a very long time and was always happy to see its evolution. That stucks completely for a quite long time and thus design and user experiance aren't up-to-date any longer.
Therefore my colleagues, friends and further environment (nearly 80 persons) decided to leave TD behind and start over again with NINE, in aour opinion a good alternative, with fresh design and a lot of developers working on it.
Sorry to say
