The Gadget: Linksys' Media Hub seems like a server, since it backs up data, gathers your media files automatically, and streams media over IP, but it's more like a super functional NAS drive with RAID support.
The Skinny: The Media Hub NAS drive is built on top of a custom linux platform that works with Mac or PC, complete with automated backups, remote access, and specific functionality, such as iTunes Server. Simillar to theHP MediaSmart Server, it presents music, photos and video in a browser based UI, that can be accessed over both local and remote connections. That means you can stream all your media from your web browser without any additional apps. It also plays nice with Linksys' new Wireless Home Audio system.
