Oh I completely agree - and protected anonymity in a manner I don't think any electronic system which stated it would somehow encrypt votes so they couldn't be traced back to the voter would ever be trusted.

Every UK ballot paper has a serial number that is logged when it is given to the voter (this ensures that every ballot paper in the count can be accounted for as properly issued). But it does mean you don't technically have a secret ballot as you can trace each ballot paper back to the voter. Legally, this can only be done in specific circumstances and often requires a court order, but there is a long-standing rumour that the security services historically went through every vote cast for a Communist candidate and traced it back, with those voter's name then added to their records.
