Is the 3K OLED screen good for drawing and notes?

Yes. It is a touchscreen with a 3K resolution and OLED contrast, and the 360-degree hinge lets you fold it flat for pen work. Check whether a stylus is included, since HP often sells it separately.

Can it replace a desktop for heavy work?

For office work, photo editing and lots of browser tabs, yes. The 32 GB of RAM and 4 TB SSD remove most storage and memory limits. It is not a workstation for 3D rendering or gaming, because the graphics are integrated.

How does the Core Ultra 7 258V compare with older Intel chips?

It is a Lunar Lake chip built for efficiency, with an integrated Arc GPU and an NPU for AI tasks. It trades some peak multi-core muscle for better battery life and cooler running than older high-power H-series parts.

Is a 16-inch 2-in-1 too big to use as a tablet?

It is usable in tablet mode on a desk or lap, but it is heavy to hold one-handed for long. Most buyers use tablet mode for drawing and watching, not for reading on the couch.

Does it come with a pen and keyboard?

The keyboard is built in, since this is a convertible laptop. HP usually sells the stylus separately, so confirm what is in the box before you buy.

Is Windows 11 Pro worth having here?

Pro adds BitLocker encryption, Remote Desktop and Hyper-V virtualization over Home. That matters for business users and IT-managed devices; home users may not notice the difference.
