you should also know that it's a double edged sword if you go with linux first vendors because you'll likely never learn from resolving your own technical difficulties that arise as a result of hardware that is not 100% linux compatible.
i learned so much from putting linux on my windows & mac hardware; that it enabled me tow work on linux professionally for the last 21 years. switching to linux first hardware 5-ish years ago made my knowledge of people facing issues atrophy, so i bought windows first hardware to re-acquaint myself.
