I use my MacBook and iPhone all day, every day. If I'm not on one, I'm on the other, and sometimes I'm on both. So I'm constantly using features like iCloud's Safari tab sync to ensure a streamlined experience as I switch between devices.
The sync feature itself, which Apple introduced last year in iOS 6, works great. But I have to admit, it would be nice if it wasn't buried in mobile Safari's Bookmarks menu. Luckily, that's not a problem anymore with this new jailbreak tweak...
