I don't think the SL7 is a like-for-like comparison even if it seems like it on paper. The SL7 is great if you want/need to run Windows - I convinced my sister to get one and she loves the battery life and low heat (less fain noise) compared to her previous devices.
If you want a nix experience, Linux support is still a WIP and progress is quite slow because of a lack of help from Snapdragon and OEMs. I expect that it might take a generation or two to get it to the point where it was with the x86 SLs.
However, at this stage, I'm tired of the quirks of Windows so the lack of nix support pushed me to get the Macbook Air for myself.
