I went with the sensible option in the end for today and had a day at home. The first spots of rain started just as I was thinking of leaving for the train station so I put the kettle on and made myself a cuppa. Quite a bit of rain since then including a thunderstorm early evening.
As I was indoors for the day, Sky Sports F1 was put on the TV and I commenced setting up the new PC, downloading all the bits I need and trying to make it function just like the old one. There's still a few things to be done - needs a Bluetooth adapter for the speakers, SD card reader for the camera which doesn't have a USB socket and I've an external drive on order for music & photo storage as the new machine only has a 240GB SSD, but I'm quite happy with the performance & space gained.
