"A web-browsing appliance that happens to run Windows, slowly."
The title uses 'Intel Core' while the description correctly lists 'Intel Celeron'. A Celeron processor is Intel's entry-level chip, designed for single tasks like email or word processing, not for smooth multitasking or any demanding applications.
This is a viable option for a secondary device if the primary tasks are simple web browsing and document editing within Microsoft Office. For someone who was planning to buy a Microsoft 365 subscription anyway, this laptop's hardware is a very inexpensive add-on.
Anyone who needs to multitask with several browser tabs and applications should find a machine with at least 8GB of RAM. A Chromebook at a similar price will likely provide a more responsive experience for purely web-based activities.
