I would caution against getting rid of laptop. The iPad File Manager is absolutely woeful and you will not be able to modify your obsidian configuration because it is stored in a hidden folder, (.obsidian), which you can’t see on the iPad, no matter what you do. I have a 3rd Gen iPad Pro and am majorly frustrated by the file handling facilities - so much so I use my iPad to log in to my Mac desktop to use obsidian.
