I think some formatting got lost. The context:

– we invented Digital Hub concept – PC as hub for all your digital assets – contacts, calendars, bookmarks, photos, music, videos – digital hub (center of our universe) is moving from PC to cloud – PC now just another client alongside iPhone, iPad, iPod touch, ...

Train of thought seems to be, "Appled invented the digital hub, with the PC at the center for all your contacts, calendars...etc - That's moving to the cloud"

Hence why its under the topic "2011: Year of the Cloud"

But it's historically accurate. You kept your photos, videos, music on your PC and moved them to and from your devices (music/video player, phone, e-reader). 2010 (date written) was only a few years after Dropbox became popular, and before it and similar products were more heavily integrated into apps.

Depends on a user I guess, I can't fill my 500gb drive even by half
