Is 4 GB of RAM enough on this all-in-one?

For basic browsing and documents, yes, but it is tight. With an Ultra 7 and a touchscreen, most buyers in this class expect 16 GB or more, and 4 GB will slow down multitasking and heavier apps.

Only light ones. The GeForce MX570 A is a low-power laptop GPU, fine for casual and older titles at modest settings, but not for current demanding games.

Is the screen good for drawing or notes?

The 27-inch touchscreen supports direct tapping and stylus-style input, which suits notes, sketches and shared use. It is a touch display, not a dedicated pen tablet, so check pen support before buying for art work.

What storage options are there?

It comes with a solid-state drive in 1 TB or 4 TB sizes. Both are fast; the larger one suits photo, video and document libraries.

Does it come with Windows 11 Pro?

Yes. Windows 11 Pro adds BitLocker encryption, Remote Desktop and domain join over the Home edition, which helps small offices.

Can I upgrade the RAM or graphics later?

All-in-ones are hard to open and upgrade. Assume the memory and graphics you buy are what you keep, so pick a configuration with enough RAM from the start.
