    The Verdict

    The Acer Aspire S24 is the best all in one computer system for regular users who do not spend a lot of time editing photographs or video, but who require a computer fast enough to run multiple Microsoft Office applications and other programs, comfortably, on a large, slim, well-designed computer. It retails for less than $1000.

    The Apple Mac Retina models and the Microsoft Surface Studio all in one desktop computers came in close to each other in terms of power and storage. Ultimately, design preference and budget will be the deciding factors in your choice between these two models. We recommend the touchscreen of the Microsoft Surface Studio for artists and editors, and the iMac Pro Retina for video editors and architects.
