I bought one yesterday. 32GB, never even really understood what an ATV really needs storage for anyway.
I wanted to wait just on principle but couldn't since I canceled cable 10 days ago.
At the end of the day what does it do? It streams Hulu Live, Netflix, and iTunes movies, and will be able to do 4K material when it becomes widespread.
Other than that, there's literally nothing I ask of my ATV - I'd still be using the ATV 3 it replaced from like 2011 or 2012 but Hulu Live requirements forced the upgrade.
