Mmm, as one of the happy 110... (I thought there would be more users with 50+ sites) I hope someone will come along to continue their great service. I always kept a dozen sites on ManageWP, just to not completely depend on 1 solution. They are just upping the pace with Orion which looks good and has promising novelties (like customer reports) But while writing this comment I updated 74 plugins using WP Remote :-)
