I just got the inspiron 13 5000 yesterday. Was about to get 7000 version,i wasn't aware of the new one. The difference is, the new one doesn't have a slot for pen, doesn't come with one, has two ddr4 slots (I've upgraded to 32gb ram), doesn't have windows button on screen, probably some other improvement internally because of the ddr4. The old one uses ddr3L.battery life is typically 8 hours light internet usage. Using dell power companion, it should give another 8 hours or more. And it's slightly cheaper. Construction seems to be the same
