Is the Yoga 7a good for gaming?

Only for light or older titles. The Radeon 840M is integrated graphics, so demanding games run at low settings and frame rates. A laptop with a dedicated GPU is the better choice for gaming.

Can the RAM or storage be upgraded?

The 16 GB of LPDDR5X memory is soldered and cannot be changed. The 2 TB SSD can be replaced, though that is more storage than most buyers will need.

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

It works for sketching and reading in short sessions, but it is heavy to hold one-handed. Most owners use it as a laptop and fold it only occasionally.

Does the touchscreen work with a stylus?

The panel supports active pen input, but a pen is not included in the box. You need to buy a compatible Lenovo pen separately.

How does it compare with the 14-inch Yoga convertibles?

It offers a bigger screen and more storage but weighs more and is harder to carry. The 14-inch models suit commuters; this one suits desk-based use.

What ports does it have?

It includes USB-C and USB-A ports plus HDMI, so most accessories connect without a hub. Check the exact port layout for your configuration before buying.
