At every CES I've ever been to, there's been one or two gadgets promising to boost your mental health. In recent years, the number of companies making forays into this space has grown, and will likely continue to do so in the future. Could it be, much like the number of people wearing heart-monitoring wearables today, everyone will be strapping an EEG to their skulls a decade or so down the line? It's more likely than you think, so it's worth asking what these devices are good for, what benefit they could bring, and where does the science end and the hype begin.
An Electroencephalogram (EEG) is a clinical tool to monitor the electrical activity of our brains. Put very simply, our minds are constantly moving ions around, and when they reach the scalp, it's possible to measure those ions. By placing electrodes on the scalp, you can record the changes in voltages pushed out by our brains more or less in real time. These voltages are commonly grouped into categories, which are often described as brain waves. Each one represents a different state of mind: Gamma (hard thinking), Beta (anxious or active), Alpha (relaxed), Theta (creative, or dreaming) and Delta (asleep).
Professor Karl Friston at University College London is one of the world's most influential neuroscientists and an expert in brain imaging. He explained that these technologies can be used to diagnose issues both in the structure and function of the brain. And while there are many technologies which can look at how our brains work, "we're a long way away from understanding the brain like we understand the heart." Broadl

Dell's XPS 14 now costs over $2,000. An AMD executive predicts that PC builders will likely make piecemeal upgrades this year, instead of building entirely new systems. And new AI supercomputers from NVIDIA and AMD are gobbling up the RAM market. At CES 2026, it was hard not to notice the dire year ahead for the computing industry, one that will likely lead to higher prices and more limited availability for consumer goods across the board.
Really, though, the show just confirmed what was apparent since RAM prices skyrocketed over the last few months, driven by demand from AI datacenters. As Samsung's marketing leader, Wonjin Lee, told Bloomberg at CES: "There's going to be issues around semiconductor supplies, and it's going to affect everyone. Prices are going up even as we speak."
Dell's new XPS 14 and XPS 16 are among the earliest systems hit by these demands. Last year's models started at $1,699 and $1,899, respectively, and we were initially told the new models would actually come in cheaper at $1,650 and $1,850. But Dell later announced a shocking price jump: The XPS 14 now starts at $2,050, while the XPS 16 is $2,200.
While it didn't take much to configure the earlier models upwards of $2,000, it's genuinely wild to me that the entry-level models are already starting there. And meanwhile, Apple still hasn't budged its $1,599 MacBook Pro 14-inch pricing. At least Dell still comes in cheaper than the $2,499 MacBook Pro 16-inch.
On the desktop front, AMD's David McAfee, Corporate Vice President and GM of Client Channel Business, noted that the longevity of the company

 Apple this week secured another victory in its ongoing legal dispute with heart monitoring company AliveCor, after a federal appeals court upheld a 2024 ruling that found Apple's changes to the Apple Watch were lawful product improvements rather than anticompetitive behavior.
