Her indoors and her sister were shopping in M&S today and taking the usual number of hours. I had an Android tablet with me so I had a look at what wifi I could "see". The various SSID's included M&S itself, which I've seen before and that I think I gave up on when it started asking personal questions to get beyond the adverts, and "The Cloud", which says it is a free service from Sky.
I fired up a browser which said "beware, its security certificate is invalid", so I listened to R4 instead.
Back home I've looked at the Cloud website (which says to always check the security certificate when you connect), and it isn't clear whether or not it requires your credit card details before you can access the free hotspots ( some charge, apparently).
Does anyone here use this and have any views? It might help me while away the sitting outside supermarket hours.
