Got one when it came out and immediately installed Projectivity launcher.
My primary reason was more memory storage as my CCwGtv & Tivo Stream 4K's suffered from too little memory storage and having to actively manage what apps were installed. I've been happy on that front.
The hidden surprise was the increased memory storage mean that I can pause Channels for an extended period of time and GTVStream buffers it easily. With tight memory storage on old launchers the pause time was miniscule.
Any other observations (pro or con) from users?
