I did forget to mention one minor tidbit from my London trip.
Was very happy to see a variety of devices with people - not just iPhone which is usually the case here in the USA.
Saw a multitude of Android devices - Moto, Huawei, Sony, Samsung, Google Pixel. Actually the girl next to me on the short flight from Dublin to London had the exact same Google Pixel as mine.
And surprise, surprise I saw a few Lumia devices as well. Guy in front of me at Buckingham Palace watching the changing of the guard ceremony had a Lumia 950. Another guy at Big Ben asked me to take his picture and he had a Lumia 650. Saw one more guy with a red Lumia 920 at the Museum of Natural History which was quite a bit of a shock.
