Rubén Caballero, a hardware engineering executive at Apple who worked with suppliers on modem hardware, has taken on a new role at Microsoft, reports Bloomberg.

At Microsoft, Caballero is serving as corporate vice president of engineering and based on his Linkedin profile, he will work on mixed reality hardware such as Microsoft's HoloLens. He is listed as part of Microsoft's Mixed Reality and AI Division, and will also work on "special projects."

Caballero left Apple in April 2019, just after Apple settled its lawsuit with Qualcomm and inked a deal that will see Qualcomm supplying modem chips for the 2020 iPhones, and after his division was folded into Apple's custom chip vision headed by Johny Srouji.

Caballero first joined Apple in 2005, and his name has been on hundreds of patents related to wireless technologies. Caballero was a well-known part of Apple's antenna engineering group, having gained public recognition following the "Antennagate" situation that impacted the iPhone 4.

microsoft won't crack the user interfacing of AR. too bad.
You really don't know what HoloLens is do you?
Dell,
Nike
Hospitals in the USA use this hardware and AR by Microsoft heavily. They’re [EDIT: wrongfully used ‘Their’] years ahead fo Apple in the AR game .

Interestingly last week I made a post of iPhones should no longer have cables within the hardware to connect components (I'll be damned to find it); seems I wasn't crazy as Cabellero (cowboy) joined a startup between Apple before joining Microsoft to do just that:

Would someone explain what she is working on in the photo? Surely she doesn't need a $4000 headset to build a potato cannon.

Pretty fairly obvious she's working on a repulsor ray prototype for Space Force. Space Force... to infinity and beyond. Beautiful repulsor ray. Best in the greatest history of all time. The most beautiful ray.

I don’t get these Mark Gurman stories that don’t seem to be much more than getting an alert that someone’s Linkedin profile changed. People leave companies and go to other big companies all the time.

You are clearly wrong! Replulsor rays have black cases. This is obviously a tractor beam. If you spent an extra 5 minutes searching the net, you would not have made that mistake.

Caballero literally means "horseman", although the term is primarily used as "gentleman".

The Spanish equivalent to "cowboy" is actually "vaquero".

Not sure if you were referring to his name or that the man "cowboys" things up... :)
