Our previous set didn't have WiFi, so adding that made a huge difference. We also installed a roof antenna to replace the flat, in-window antenna we'd been using.
The TV works fine. The closest thing to a negative might be with the input selection. You press INPUT and are presented with all the choices, but before you get a chance to locate the one you want, the choices quickly disappear and it's necessary to repeat the process with a finger hovering over an arrow so you can immediately start scrolling, in order to keep the list on the screen.
