It also has a backlit keyboard, aluminum casing on top and probably PC + ABS casing on the bottom, AMD 3 4300U 4 core CPU, Windows10 pre-installed, 2 year warranty.
I can buy a refurbished T480 for ~500 euros with the 1Tb SSD and 16GB RAM + 2 year warranty for the Thinkpad and 6 month warranty for the battery from another vendor. Or a new L14 G1 with 8gb RAM, 256 GB SSD, AMD Ryzen 5 6 core and backlit keyboard for ~670 euros (no soldered RAM) from another vendor.
Should I bother to send this E14 for incorrect specs (the discrepancy in which basically may not matter much for me for now)?
As for the SSD it comes down to the units used by HDD and SSD manufacturers vs the ones used by operating systems, which is indeed misleading and bordering on fraud imho. But, again, your laptop certainly do contain a 1TB drive and you will find the same discrepancy in reported capacity even if you buy a 1TB nvme drive and install it yourself.
Enjoy your new laptop. Thinkpads are awesome.
