I would say that in general terms if one is a very frequent flyer and for their sins knows more than the majority of the passengers about technical aspects of a company and it's aircraft, then you can make informed decisions about which airlines/routes/airports to use and those NOT to use. The 787 is a fantastic aircraft, billions invested and tested, new systems, new materials and on and on. It experienced problems earlier in it's development, was delayed a few times and finally brought into service. However, since then there have been way too many incidents, both major and minor covering different airframes and airlines. If there were not SO much riding on it's continuing introduction to service it might well have been wise to complete further intensive testing.
I have the feeling that some of the agitated posters are working for airlines that have the 787 in their fleet. If PAXboy feels with his extensive travelling experience that he'd prefer to not travel on a 787 until the recent faults are remedied then that's his choice. It's not personal against Boeing/engineers/pilots/crew/et al, but it IS a personal decision, and not without merit.
