What can you actually replace on the X395 that you can't on the X1? RAM is now soldered and that used to be the only difference from what I remember. I currently have the T460s and like the size. The T495s would be the equivalent but looking at it they are all about the same size now. I thought the X395 would be smaller.

Either way the X395 and T495 both have a maximum of 1080p screen. I have a 1440p and will never go back. In fact I want the X1 for the 4K screen and the beefier chassis. I'm on my third panel and they all develop white spots from the cover not being protective enough.
