Broadband – it varies from a damp piece of string to fibre, it just depends where you live. Mobile broadband may be a better option.
A blocked road can mean there’s no option other than to turn around as there may not be a detour but it’s rare. At least there are very few, if any, traffic jams. I don’t think it’s a problem.
I only wear a midge hat around once a year in the garden. Just keep moving faster than midges and you’ll be fine.
Food shopping is a bit restrictive with the Coop however Tesco do a click and collect where you meet their van in a car park. It can be difficult at first not walking around a supermarket to choose what you want although not going to a supermaket has its advantages (if you hate shopping). For other stuff you’d get used to buying online and there’s the huge advantage that Hermes and Yodel don’t deliver to Skye, they use local agents instead.
