Our take on the HP 21.5" All-in-One Desktop Computer

This is HP's budget all-in-one: a 21.5-inch 1080p screen, a white chassis and a two-core Intel Celeron J4025, sold in several memory and storage configurations. The screen is sharp for the size and the footprint is small, but the Celeron is a light-duty chip, so it suits web browsing, email, documents and streaming rather than heavy multitasking or gaming. Against rivals like Dell's Inspiron all-in-ones and Apple's iMac, it trades speed and display quality for a compact, low-demand design. Buyers like the tidy single-unit setup; the common complaint is that the processor feels slow once several apps are open.
