Yahoo’s top mobile exec, Marco Boerries, is departing Yahoo, according to an internal email obtained by BoomTown that he sent to some staffers on Sunday.

I have also confirmed Boerries’s departure with company insiders familiar with the situation.

In a post Monday on a management restructuring at Yahoo (YHOO) that new CEO Carol Bartz is likely to unveil to the company this week–sources tell me it is now set to be announced internally tomorrow–I noted that Boerries was one of the more likely high-level execs to go.

He has been the EVP for the Connected Device Division at Yahoo for four years, coming to the company in 2005 with the acquisition of VerdiSoft. He also had earlier sold another software company to Sun Microsystems (JAVA) in 1999.

Nonetheless, many inside Yahoo expected him to go with the changing of leadership recently, after almost two years of turmoil at Yahoo. Like many, he reportedly wanted to leave earlier, but felt loyalty to former CEO Jerry Yang.

I wrote:

Boerries, a talented but more freewheeling exec under Yang, is another question all together. Already wealthy from selling several companies, the entrepreneurial exec is most often mentioned by sources as someone unlikely to stick around, especially if Bartz tries to rein him in more. (In addition, Boerries has family issues requiring that he spend a lot of time in his native Germany.)”

In his email, Boerries did not mention Bartz, but did indeed mention his personal issues.

“With a very heavy heart I have to tell you, that I will be leaving Yahoo!,” Boerries wrote, attributing his departure in an email titled “Personal Update,” to issues related to his family.

Because of that, Boerries has more recently been splitting his time between Northern California and Hamburg.

In the note to staff, he also noted all the successes Yahoo has had with its mobile and other device efforts.

It’s unclear what the impact of Boerries’s departure on Yahoo’s Connected Life unit will be.

But it seems more likely than not that Bartz will cut back, given that it is harder to monetize now and also because Yahoo does not have its own device, as both Apple (AAPL) and Google (GOOG) do, which might help it create a more virtuous ecosystem.

Still, Yahoo has some extremely interesting products in the mobile space and, as is typical, really well done, such as many parts of its oneConnect service for smartphones.

In addition, Boerries unveiled a pretty interesting Connected TV effort at the Consumer Electronics Show in January, although this is also an area still struggling to find a lucrative business model.

Here’s a video of me interviewing Boerries, as well as Yang and outgoing President Sue Decker, about Connected TV:

Marco

As BoomTown did last year, I took to the much-less-crowded floor of the Consumer Electronics Show in Las Vegas last week with tech review kingpin Walt Mossberg and Mossberg Solution columnist Katherine Boehret to get their take on the scene.

Big news for Walt was the Palm Pre launch and the Yahoo Connected TV initiative. For Katie, it was a $2,000 cellphone.

As I also said last year, I jokingly call Walt the “Brangelina” of CES, since he is stopped constantly on the floor by fans who want to meet him in person and those who just want to kibitz with him about the latest and greatest trends in the tech sector.

So, here are this year’s video ruminations:

Usually, BoomTown plays the stalker of Yahoo CEO Jerry Yang. But, with an interesting product to show off, this time he invited me and also Walt Mossberg to take an on-the-floor look-see at the company’s new “Connected TV” effort yesterday.

Wading into what has been a longtime dead end for many tech companies–bringing the Internet to the television–Yahoo (YHOO) has struck a deal with South Korean consumer electronics giant Samsung and other major television makers to put its software in televisions to link them to the Internet.

Using an onscreen dock, Yahoo is presenting its own services (like Flickr) and those from outside Web sites (YouTube) with this “widget engine.” With a regular remote, you can click through these applications easily and launch them in a side screen.

Yahoo hopes to create an entire ecosystem of these widgets, similar to what is occurring with the iPhone.

Publishers and vendors can use Yahoo’s open technology, although the company will offer monetization services, keeping itself at the center of the platform.

In the short amount of time I used it, it’s a nice effort and an important one if Yahoo is to try to lead in being a key player in devices other than computers.

Here’s the video of me talking to Yang (check out his attempted scary stare at me at the start!) and Yahoo President Sue Decker about Connected TV, along with an interview with Yahoo’s point man on other devices, Connected Device EVP Marco Boerries.
