Pi4, power supply and HDMI lead on order.  I was hoping that they would arrive today, but DHL seem to think that they would prefer to spend their day at their local depot.

After spending a day at the depot, it was sent out for delivery today. According to the 07:58 email, it should have been with me between 10:19 and 11:19.  According to the tracking site, at 10:30 I was the next drop. At 14:20 I gave up waiting and went out.  Parcel arrived at 14:40, and was left next to the front door, fortunately not obvious from the road.

Noting the discussions elsewhere on the thread, I though the following might be useful.  I take various readings every minute including the CPU temperature, the ambient temperature and the CPU loading.  Having now had the Pi4 installed in its new home, the following is from the first full 24 hour period (min max mean) :
CPU Temp        36.5    51.1    41.1
Ambient temp    12.7    18.5    15.6
CPU load %      0.00    1.31    0.09
It will be interesting to see how that works out over a longer period.
Performance wise, it is a vast improvement.  Prior to the upgrade on matplotlib, I had one job running every 10 minutes, taking 5-6 minutes (11-12 minutes post software upgrade).  That now runs in under 1 minute.
