I have been using and upgrading Pocket Informant since version 2. I recently installed version 2 on an old ipaq for a laugh and it was testimony to how far this application has come.
On installing the latest 2005 version I have to say first; it looks so much better, polished and professional, fantastic.
But... it has become bloatware. This is picked up by the way it now slows down my XDA II with crawling screen refreshing.
I know that WebIS developers have to come up with something new to keep the money coming in but you just cannot improve this application any more without making it too demanding on your resources.
