Out of stock

In my never-ending search for gadgets, I want something I can use to help me write on the tube. This is not a simple task, both in the fact that I can't read my own writing on a good day and the bumping of the tube makes it simply not worth the effort for pen and paper, and in the fact that what I want either doesn't exist or is out of stock. Yes, the entire world of electronics is out of stock.

My journey so far ( cut for those who've already passed out from boredom )

So, UK folks, when you shop for computers in real bricks-and-mortar shops, where do you go?
