Fog:
Not looking forward to loosing my T-Box, but is there anything available that will fully replace it.
Short answer: no.
Long answer: there are other options, each of which come with new features but also restrictions.
A service from Sky requires a dish on the house, a box per room with all the pricing that goes with it. Plus a great ugly power sucking box with an unknown future (Sky have already said they are working on new methods).
VodaTV is actually very good and has a mobile app but not yet for AppleTV, AndroidTV etc. But there are restrictions on what content can be 'recorded' - a lot of FTA can't be recorded, recordings have forced expiry etc - plus there are ongoing bugs as with any iptv service.
After that the options become quite fragmented
