Is the 16-inch screen good for photo and video editing?

Yes. The 3200 x 1800 resolution gives plenty of workspace for timelines and layers, and the 120Hz refresh makes scrolling and motion smoother. The touchscreen adds direct control for drawing and marking up.

Can I upgrade the RAM later?

No. It ships with 16GB, which is also the maximum supported, so buy the configuration you need up front. The 1TB SSD is the storage you get.

How does it compare with a 14-inch ultrabook?

It gives you a much larger, sharper screen and dedicated NVIDIA graphics, which ultrabooks usually lack. In return it is heavier at 4.3 lb and its 9-hour battery is shorter than the best small laptops manage.

Does it have a good set of ports?

It covers the common needs: USB-A, USB-C, HDMI, Ethernet and a 3.5mm headphone jack. That means fewer dongles for monitors, wired networks and older accessories.

Is the keyboard backlit?

Yes, the keyboard is backlit, which helps when working in dim rooms. It also has facial recognition and a fingerprint reader for logging in without typing a password.

What kind of buyer is it aimed at?

People who want one large-screen machine for creative work, study or design and don't need to carry it far every day. If portability and long battery life come first, a smaller laptop fits better.
