The Dish Network TV was a major disappointment. It did not work at first. Then it started to work, but would consistently freeze up. This would cause a reboot of the system. The only amusing part of this was that it was Linux system and I got to repeatedly watch the Red Hat reboot sequence. I was never so annoyed to see that freakin' penguin... I've flown JetBlue on several occasions and always enjoyed DirecTV on it with no problems. Actually the first time I flew JetBlue was the night that the Iraq War began (Shock and Awe! Go America!!) Talk about a surreal experience: watching live coverage of the beginning of the war while on a jet (flying to Vegas for the beginning of March Madness...) I digress.
The free music was not so bad actually. I was lending my MacBook to Michael, Jr. so he could watch some DVDs, so I was going to listen to my Nano. I wanted to listen to Coldplay's latest, so I was distressed when I realized that I had loaded up all of Coldplay's music except Viva la Vida. However, I noticed that Delta had that album available, and so I listened to it. The sound quality was even worse than the average sound quality of the Nano, but I still appreciated it.
I didn't try out the for-pay entertainment. Michael, Jr. finished watching the Leap Frog DVDs that he wanted to see, and wanted to draw. So I got the MacBook back and reviewed some chapters from a couple of books-in-progress. I did notice that Delta will begin offering Wi-Fi on flights for $10-13 per flight, depending on the length of the flight.
