A lot of rumours swirling about.. The Evening Echo reported Apple was in 'advanced negotiations' to secure one of the corner units in the Opera Lane development in Cork, right on Patrick St.; as well as locations on Grafton St. and elsewhere in Dublin.
While it doesn't seem like good timing, Apple could sign a long-term lease on a premium store units for a bargain price these days, it's the perfect time to start up if you want to keep costs low.
(Since that story, I've read it may be an Apple APR rather than an official Apple store, so who knows..)
PC World do have Apple stores-within-a-store; which are styled as Apple Stores, but are quite small and a bit lacking.
