Was getting annoyed that some of the UK apps I like to use still aren't ported to the CCwGTV (Channel 4 for one) and had to do some kludgy things to try and access those services (and sideload other that did have apps that are out of the Google Play Store NZ 'world').
Already had an elderly - but still functioning AFTV, so bit the bullet and bought the new 4k max model yesterday.
It installed about 3 updates first time on and then to business.
Logged it in, installed all my apps from various locations that were already against my amazon account (I wont explain how you can curate a collection of apps from various locations here), and apart from the business of logging them it was all go.
I run kodi, which is the only thing I had to sideload and there is always that head scratching bit about adding a network samba share to kodi.
So all up and running now. It is definitely smoother/faster than the CCwGTV and seems to have better wifi.
The CCwGTV seems to have micro glitches when playing a lot of apps - probably some sort of mismatch between frame rates and display rate - but seems fine with the AFTV.
The CCwGTV will probably go upstairs to the bedroom TV to replace the old AFTV Gen 1.
