I just upgraded to the ATV4 last night. So far so good! It's noticeably quicker than the ATV3, more responsive, improved interface, much nicer remote, nice added screen savers/sound effects and little touches like that. The streaming just seems...stronger, too. Hard to describe. It just looks better and seems to stream the Watch ESPN app...better. Not a bad upgrade for $119! (I got Best Buy to price match the Radioshack online deal). My only question...is there a remote app for the ATV4? I remember I used to be able to launch the Remote app on my phone and could type and swipe on the ATV3. I can't seem to get the Remote app to recognize the ATV4, and it's annoying having to type out email addresses and passwords on that thing. Am I missing something?
