Don't think so...
From my point of view, and having played with the betas, iOS5 is going to make a big difference to Apple TV usefulness, especially in the UK, where the other movie rentals aren't available. All of a sudden, you can stream BBC iPlayer and 4OD Player to your TV through the Apple TV, rather than hard-wiring it. And virtually all video embedded into websites can be streamed as well.
Personally, I'm hoping that the hobby is serving as a test for one of the components that will go into the Apple Television. I'm imagining this world where my iPad is my TV remote, and I can scroll through TV listings for the past as well as future, and set my TV to record programmes, allowing me to watch them on my 1080p TV, iPad, iPhone or iMac any time. And where my Apple TV2 in the bedroom will stream anything from my main TV.
Back to work...
