ANDARIAL, you are barking up the wrong tree.
There are still uses for analogue. For example, it is possible to distribute a Sky box signal around your home using a simple (and cheap!!) aerial distribution amp. You can't do that with a digital. There's no piece of consumer gear that generates a digital signal (DVB-T / DVB-T2).
Just because YOU don't have a need for analogue doesn't mean that others don't.
Also, twin tuners refers to the ability to tune in to two signals simultaneously. This is for the "watch one, record another" function. It does not refer to the type of signal. So if a twin tuner product has the capability to receive terrestrial and satellite and cable, then it is still a twin tuner device. Similarly, even if a Freeview recorder can only receive digital terrestrial then it is still a twin tuner device.
