In terms of quality of seat and entertainment, I think United's business class is quite competitive. The screen is huge, and the controller is nice and response. There's a huge amount of content to view. However, I think it's time to fix up the iPod integration.
Take a look at the picture, which I snapped on one of my recent flights. When was the last time you saw somebody with one of those devices? It has been years! Problem one: the image doesn't represent reality. Those devices aren't even on the market anymore.
The next surprise comes when you actually plug in any modern iPod or iPhone. Nothing happens. The system doesn't detect the device. Your phone / iPod will get charged, but that's all that happens.
We've got a picture of something that doesn't exist and the functionality doesn't even function. Honestly, given the proliferation of iPads, Kindles, iPod Touches, and everything in between, I don't think United even needs to offer iOS / Android / whatever integration. Just remove the section from the AV system so it's not confusing… and give us our darn satellite based WiFi, Jeff Smisek!
