As of tonight GMail seem to be making their Mail Fetcher feature available to regular GMail accounts - at least it’s now available on the two non-related, US based, accounts I use 
Mail Fetcher allows you to configure GMail to retrieve email from other mail accounts via POP3. When retrieved, external mail may be left on the server, automatically archived, or have a label applied. (The last option is a nice way to highlight non-GMail items in the inbox).
