I've been using a few main line trains to get around over the last few days. It made me decide to restart my Kindle newspaper subscription.
The previous one just stopped after I had another one of those card alerts where they phoned me to say they thought someone had been using my credit card.
That was way back in November and I think the bank might have been right on this occasion.
I agreed to let them stop the card and ordered another one but then some previously agreed payments also stopped working.
The Kindle newspaper was one and its only recently that I've noticed it again.
It's most useful when I'm travelling and only have intermittent connections because the paper downloads itself in a few seconds and is then fully available offline.
So planes and trains are the best uses.
Trains especially because the available space to read gets smaller and smaller as one approaches a busy destination.
