I didn't realize you were involved in this company until I read your other comments. It is unclear what "You're locked into some of our custom components" means. Can a average techie, maybe someone who is comfortable opening their laptop to add RAM or new storage but wouldn't be comfortable making any other hardware changes, upgrade this with off the shelf parts? If the answer is yes, that should be in your marketing material. If the answer is no and you can't commit to selling these custom modules, then I stick to my original point.
