I'm so tired of these garbage 737s flying in and out of IAH

United clearly knows us IAH regulars don't have many options. 8 out and backs in the last month (2 first class remainder E+) and at least half have had some issue- broken tray table, non-functional wifi, broken infotainment...now the minor annoyance of no seat back storage. Abysmal showing from United. When are these planes getting fixed?
