I currently have 2 model B's and one A. I had an unsupported SD card in the beginning, which annoyed me (it wasn't mentioned anywhere that this could happen). But you can check here if a card will cause problems: http://elinux.org/RPi_VerifiedPeripherals. After finding a good one: no more problems.
I also blew up a cheap chinese power supply 1A/5V but since I have been using a 2.5A/5V power supply I have had no problems (I back feed it via the "front" usb port, the hub has power on the input line, although that is not recommended.)
After that I never had any problems, 1 has been running OpenElec (XBMC) for more than a year now. Another one switches my lighting, also never any problems (running 24/7 for over a year), it is fed via the USB in my router. One of them also spent half a year in a data-center (http://raspberrycolocation.com/), it never failed.
There is no excuse for being treated so poorly on the forums but I have the feeling like you just had bad luck so far. It happens, My Moto G had yellow pixels and a failing audio system. Still a good phone judging from the experience of others.
If you really just want it to work out of the box, buy the recommended power supply (2A/5V I think), a good SD card or a preinstalled one with NOOBS (http://www.raspberrypi.org/help/noobs-setup/).
