As Jeremy says, your paper subscription to the BAA Journal actually already includes access to the electronic version (in PDF format) which you can download here: https://britastro.org/journal
So, feel free to try reading it on your tablet and see how you get on with it.
For the record, I switched to an electronic subscription a few years ago when I was living abroad and was anxious not to accumulate too much “stuff”. But Jeremy’s point (1) is absolutely right: I read far less of the Journal now than I used to.
In case you’re wondering, the December Journal isn’t available electronically yet, as it normally appears online shortly after the paper copies arrive.
