Intel dives into the Internet of Things, but still has a weak PC market to deal with

If you set foot in Intel's CES booth this winter, you probably sensed a theme: the company is deeply, almost manically, focused on the Internet of Things. Sure, Chipzilla was showing off some tablets and phones, along with a shelf full of Ultrabooks, but the highlights of the show were all a little more unusual. Think: a light-up "smart mug," headphones that can monitor your heart rate. An internet-connected baby onesie, for crying out loud. It was obvious the company was a bit obsessed, and now it's clear why: the Internet of Things is currently the most promising piece of Intel's business.

Take the company's first-quarter earnings, for example, which just came out today. Intel's revenue from PCs, normally its biggest money maker, dipped 1 percent. At best, you could say the computer business is flat but really, "decline" is the more accurate word -- the PC industry faced its steepest-ever drop last year. Meanwhile, revenue for mobile products (read: phone and tablet chips) plummeted 61 percent. Yikes.

But the Internet of Things -- now that's a bright spot. Sales there were up 32 percent from the year-earlier period. We know, we know: that's partly because the Internet of Things simply wasn't, uh, a thing last year. But the numbers do suggest that where there's demand for some sort of "smart" object, Intel has a strong chance of getting one of its chips inside. That's good news for Intel, but maybe not good enough: even with a booming smart coffee-mug market, connected objects still accounted for just 3.8 percent of Intel's overall sales last quarter. How long will it take smart baby onesies to catch up before Intel doesn't have to use PCs as a crutch? And what's the deal with that tanking mobile business, anyway? We'll let you chew on that while we wait for Intel to host a conference call. We'll update this post if we glean any new details.
