Is the RTX 4070 wasted on a 1080p screen?

No. At 1080p the RTX 4070 runs most modern games on high settings well above 60fps, and the 144Hz panel shows the extra frames. It leaves headroom for future titles, though a 1440p panel would show more detail.

Can I upgrade the RAM and storage?

Yes. It ships with 16GB DDR5-5200 across two SO-DIMM slots and a 1TB Gen4 M.2 SSD, and both are user-replaceable. Check the slot count before buying a kit.

How long does the battery last?

Expect only a few hours of light use from the 53.5Wh battery, and less when gaming. Keep the 200W adapter nearby for anything demanding.

Is it too heavy to carry to class?

At 2.25 kg plus the 200W adapter it is on the heavy side for daily commuting. The included backpack helps, but a lighter ultraportable suits all-day carrying better.

Does it come with Windows and a backpack?

Yes. Windows 11 Home is preinstalled, and an MSI gaming backpack is included in the box.

How does it compare with the Katana 15 RTX 4060 model?

The RTX 4070 version gives a clear step up in frame rates and more CPU headroom with the i9. The 4060 model costs less and runs cooler, so pick it if you play lighter titles.
