Thoughts? urgent

Urgent. Need help to decide which one to buy as a student (can also suggest another one as long as no more than 2.1k).

Mom told me to get the one that can: -last a long time -store many stuff -run faster -long battery life

What I'm going to use it for: -making lab reports -making notes -browsing (multitasking) -light gaming (just an extra, if cannot then that's fine)
