Tried papers on tablets
They are universally rubbish. The Times app is OK - ish - but the Sunday Times app is atrocious, it's a series of stitched together images mainly, meaning each section is massive to download.
The whole point of sunday papers is to completely cover every flat surface in your house with newsprint, so cramming it all into a small tablet doesn't actually work that well.
The only time it is really useful is when you cannot get the real thing - probably abroad. In that case, the huge downloads really make it suffer. Who wants to wait 3 hours to download the Style supplement?
Finally, the price of most newspapers is outrageous. In London, we get served with free newspapers - not the Metro, but the Evening Standard is actually decent quality. The BBC has impartial (well, BBC impartial) reporting of all main events.
The only paper I actually regularly pay for is Private Eye, which is a magazine anyway. Private Eye, Evening Standard, BBC, The Register. Sunday Times on a sunday if I have 4 hours to kill.
