Buying a Business PC in 2026? 6 Trends That Will Impact Your Choices ...
www.pcmag.com
It’s not a revolutionary year, but steady gains in chips, displays, and AI features are reshaping the computing market. Here's what’s worth paying for and what you can skip. By Michael J. Miller ... https://www.pcmag.com/articles/buying-a-business-pc-in-2026-6-trends-that-will-impact-your-choices Email Comments The one that stands out the most is Lenovo's venerable ThinkPad X1 Carbon. For its Gen 14 Aura Edition, it sports a new design, with what the company calls a "space frame," including a two-sided motherboard. This allows for more parts to be easily replaced by an IT department, including the keyboard, battery, and even the ports. With the new XPS, Dell is emphasizing performance and battery life as opposed to thinness and weight. I'll be interested to see Dell's enterprise offerings—now sold under the Dell Pro branding—in the year ahead. (I expect it to announce these soon.) Samsung Galaxy Book6 (Credit: Michael J. Miller) Of course, we're also seeing OLED displays in lots of other machines, including the ThinkPad and EliteBook lines and the Asus ExpertBook. And I've found that slightly thicker offerings, such as Dell's Pro Plus line, compared with its Pro Premium or the ThinkPad T14 series versus the X1 Carbon, can actually perform a little better with the same processors, probably because the extra space allows for better cooling.
