The JBAA is one of the few journals/periodicals that I continue to get as a physical thing. I’ve been a member of the BAA since 1974 and my run of Journals goes back getting on for 50 years (scary) but still only takes up a couple of metres of shelf space so storage isn’t really an issue. A bit like Jeremy I find that I don’t read digital copy in the same way as physical, its much more a quick scan then store it on the computer to look at another day. I tend to embrace new technology but reading for pleasure is still definitely physical books for me and I feel the same way about the Journal.
As Dominic says, you have access to the electronic Journal now so can try it and see how it works out.
