Heya and welcome from a fellow London newbie!!
I totally understand where you are coming from, it's all a bit overwhelming at the beginning. I am sure I will get my head round it soon. I am also a fellow geek.
Downside is, I work with lots of geeks and they have all switched to vaping. And they always have all this new shiny stuff. I can see myself spending a fortune soon.
Good thing is, I prefer pink sparkly things, my purchases should be safe from them :-)
