Lufthanza is offering wireless internet on their planes. I am sure others will follow.
This gets me more excited about flying across the pond than before. Mainly, because I can get online and waste the hours away.
Also, I can combine this with the box that you can plug your TiVo into which broadcasts it online.
Now, I can be sitting at 30k feet, watching my TiVo. That is cool :)
NOTE: there is a primer on the new TiVo To Go setup in TiVo 7.1
