A T440 for my IEM

I have a Truthear Blue + Meizu USB-C DAC, and I put on Marketplace, someone offered a T440. Should I trade? Im very skeptical about the 4gb of RAM soddered, 768p screen, original batteries (he says around 2:30H of battery life) and only 2 core CPU. I wish it could be the T440p, T480 or an X280 wich I am searching right now, but its not.

Edit1: For you guys with Haswell CPU, could you guys tell more about battery life? My P15 Gen 1 only goes around 3-4 hours, so if it can go more, I would have a use case for it!

SOLVED: I will not be trading, its just not worth it for the T440.
