Apple has just posted three videos to YouTube that it first aired during a special event in Cupertino on Thursday morning.

The videos highlight two new products that Apple debuted: iPad Air 2 and iMac with Retina 5K display. While two of the videos are typical 30-second ad spots, the third video, specifically for the new iMac, introduces Apple's latest desktop machine and provides a brief overview about what's new and different compared to the now-older iMacs.

Instead of featuring Jony Ive, head of design at Apple, in front of a minimal white backdrop, the iMac video shows Dan Riccio, senior vice president of hardware engineering, discussing why Apple updated its all-in-one computer with a stunning 5K display and faster processors. Check it out above, for yourself, as well as the two ad spots below for iPad Air 2 and the evolution of Retina in regards to the iMac.
