I'm eagerly awaiting the 7.8 update (although realistically I expect to upgrade to a WP8 device before 7.8 is even available from my carrier), but my wife has expressed distaste for the larger tiles based on what she's seen in commercials. Since I'm her "IT pro" I always make sure here phone and laptop are up-to-date with the latest security and stability enhancements.
To my knowledge 7.8 brings the updated start screen and little else. Since she's not due to upgrade for another year, my question is would she be missing anything important (again, such as security or stability fixes) by not upgrading to 7.8?
