Like you, I don't have a problem with the cost - as I understand the economics of the bundle system and how it's resulted in a golden age of television programming (and sports coverage!)
I have DirecTV and have been satisfied with the customer service. I've had one significant technical issue in 15 years that took a couple of visits to fix. But they do a great job of continually upgrading their equipment, features and amenties. Whether it was releasing DVRs before most cable companies, whole home DVR, wireless, streaming features of the tablet a high quality app...they've done a great job.
And most of all 'it just works'. I've played around with alternate delivery systems - Roku, Amazon TV, Fire Stick, etc - but they all suffer from an a clunky interface. Any alternative has to meet the 'grandma' theory. If the parents or inlaws are visiting or we have company - can they operate the TV without me having to explain different menus/remotes. Until something gets to that system and still has the depth of programming and sports as the current system, I'll keep what I have.
