Is the touchscreen worth having on this laptop?

It helps with forms, scrolling and light drawing, and the 1920x1200 panel is sharper and taller than a standard 1080p screen. If you never touch the screen, a non-touch model of the same line is lighter and simpler.

Only light ones. The Ryzen 7 uses integrated Radeon graphics, so esports titles and older games run at low settings, but modern 3D games will struggle.

Is 16 GB of RAM enough?

Yes for study, office work and heavy browsing. It also leaves headroom for years of Windows updates, and the memory is soldered on many Slim 3 models, so buy the capacity you need up front.

Does it have a number pad?

No. The keyboard fills the width without a numeric keypad, which keeps the keys centered under the screen. Buyers who enter lots of figures should look at a 15.6-inch model with a numpad.

How does it compare with the IdeaPad Slim 5?

The Slim 5 adds a metal lid, brighter display options and usually a larger battery. The Slim 3 costs less and covers the same basics, so choose it if budget matters more than finish.
