I'm been saving up for a laptop with as much security as possible, and I'm about to purchase Libiquitys Taurinus X200: https://shop.libiquity.com/product/taurinus-x200
is there any reason why I shouldn't go through with this purchase? And Can I get advice on any additional steps I should take?
I don't understand why you would want to buy a Librebooted laptop. For $100 you can buy an X200 and everything you need to flash Libreboot onto it.
