Apple Mac, Wheres the hash (#) key!

I can't believe that in the age of Twitter Apple hasn't got round to printing the hash # symbol on the number '3' key. At least for the UK rMBP (retina Macbook Pro) keyboard i'm using anyway! They've done it with the euro € symbol...

It's Alt + 3 for anyone wanting to know what it is!
