I used to be really into jailbreaking... I'm sorry to say it, but I think Apple won. I think I'm done with jailbreaking. It's too big of a pain. Apple has really stepped up updates... And I don't like having to wait or miss out on what these updates have to offer. Not to mention that the process of updating with A jailbreak is a pain in the ass.
I can accomplish most of what I want without a jailbreak now... I think the ability to sideload apps pretty much puts a nail in the coffin for jailbreaking... At least for me... It's just not worth the hassle anymore.
Even if I was still into jailbreaking.... There is no way that I would jailbreak my Apple TV at this early stage. I expect that there will be a lot of updates over the coming months. I think those will be more important than anything that can be game through jailbreaking.
Just my 2¢
Which is all good of course! Many of us really really use some of the more obscure parts of jailbreaking and thus particularly enjoy it. Things like AirPlaying apps that restrict it are just the tip of the iceberg.
I guess I've never understood the people that say it's a hassle. Once its done, it's done. I personally hate being on the bleeding edge of Apple updates these days anyhow.
Anyways, to each our own of course!
