HP All-in-Ones Pentium Silver J5040 Editorial Review
The HP 21 All-in-One PC is a great computer for home with an easy setup process and a big, clear picture. It comes with the current version of Windows software and related programs. The computer is not touchscreen, and it does not have a DVD writer or player. Some users had issues with the computer not working or needing to reboot frequently. The computer works well for basic tasks such as email, browsing, and word processing. It is not suitable for gaming. The computer is capable of running Zoom conference program and can be upgraded to Windows 11. The RAM size is a limitation for some users. Users wish for a wireless mouse and keyboard option for a clutter-free look. The HP 21 All-in-One PC is a suitable option for an elderly writer with limited space.
