Thanks for answering people.
I've actually had campervans for a few years and camped in tents before that, I've got no problem with being closer to nature .. Things like washing, boiling water and toilets don't bother me ... but I've never done it for extended periods of time, with nowhere to return to.
Looking around this flat, I have 6 plugs for the hifi (separates) and 32" telly & DVD. About the same for the computer, printer, monitor, scanner, 2 large external hard drives, router etc. (I kinda dislike laptops). I also have a digital SLR and mobile that both need recharging regularly. I too have a sewing machine, and also an electric guitar. That's just the main stuff, the list goes on ...
So all in, that's quite a lot of plug sockets and quite a lot of room taken up. I would definitely have to compromise somewhere.
Ah but how true is this? It seems that a great many boaters look out of their windows and just see other boats.
