Ambivalent
I've used several services recently; car tax renewal, driving licence renewal, worked very well indeed even from overseas. The local council registration also works well. If they can provide the same user experience, with appropriate security for other services, then I would say good luck to them.
However, when I last tried to submit a Tax return, it was significantly less satisfactory. In fact, I gave up half way through, downloaded the forms, filled them in and popped in an envelope which I dropped off at a local post box, all in about half the time that I had spent trying unsuccessfully to enter the details online.
We will see what we see.
