What happened to tablet computers and ultra-mobile PCs that run a full desktop operating system such as Windows or Linux instead of a mobile OS? Modern hardware is far more powerful and efficient than it was in the 2000s and 2010s, so why aren't compact tablets with desktop software more common today?

The product categories settled into different roles. Phones and conventional tablets offer simple, efficient, tightly integrated software, while laptops provide a more flexible desktop experience with keyboards, ports, and unrestricted software. A full desktop OS on a touch-only tablet can work, but most people prefer a keyboard and trackpad for serious work, so the market for the hybrid is relatively small.
The main technical limits are still heat and battery life. A thin tablet has very little room for a large battery, cooling system, ports, or upgradeable components. Desktop-class processors can be extremely fast, but sustained workloads turn that performance into heat and drain the battery quickly. A slightly thicker convertible laptop is usually a better compromise.
Cloud services, capable mobile operating systems, speech-to-text, and better phones reduced the need for a tiny computer running a full desktop OS. These machines are still useful for specialized jobs, but they stopped being the next big consumer category. Gaming handheld PCs and compact Linux-compatible tablets now fill part of the old UMPC niche for enthusiasts.
They never really disappeared. Devices such as Microsoft Surface models, Dell Latitude tablets, Lenovo Yoga systems, HP convertibles, and newer machines like the Asus ROG Flow Z13 still combine tablet hardware with a full desktop operating system. They are just aimed at business users, artists, and enthusiasts rather than the mass market.
Software design also held these devices back. Windows and most desktop applications were built around a mouse and keyboard, while touch interfaces need larger controls, better gestures, and simpler workflows. Windows 8 experimented heavily with a tablet-friendly interface, but many desktop users disliked it. Later versions restored a more traditional desktop experience, which made them better laptops but less elegant as pure tablets.
That said, modern Windows tablet mode is much better than it used to be, especially with a stylus and apps such as OneNote. Convertible tablet PCs are still very useful for handwriting, drawing, inspections, field work, and taking notes.
There are also plenty of smaller manufacturers making compact systems that support Windows or several Linux distributions. The selection is broader than it looks if you search beyond the major brands.
