Who wants to try them first? They use the new SMR Technology to get more Storage out of a Platter. They also really put a new price tag on large HDDs, they are not expected to ship before February 2015 and they already have, by far, the lowest €/$ per Gigabyte Value...
Before you get too excited, those drives have some limitations. Due to those limitations you should not use those drives with often changing data.
