It is lighter than my 13” 2008 MBP but it about a pound heavier than current 13” versions. It weighs the same as the 15” it replaced (4.02 lbs). The big deal with it is capacity and speed, up to 64Gb of RAM and up to a 8T SSD. That’s heavy lifting for a laptop. It is expensive, very expensive when loaded. I paid about $2100 for my 2015 MBP with 16Gb and a 512 SSD, $500 or more for a much faster larger version with 1 T SSD is not so bad. But again, I don’t need it right away. The 16” screen is a lot bigger when side by side, and it’s quite a bit brighter than my 2015. They are not upgradable, just like all the newer MBP’s. I’m hopeful the 13” gets similar upgrades in the next year or so, but I’m not holding my breath, nor am I getting any younger. I truly hate the butterfly keyboard.
