So I need a laptop for studing so office apps snd web browser. I was thinking about used thinkpads or similar. I would need it for 5years So what processors gens are too old. Like I know from desktopside that intel 12-14 gens are wery powerhungry is it the same in laptops. And would something older intel 10-11 gen still work okay after 4 years. And how powerfull is something like ryzen 3000 series nowdays

Edit: For people suggesting linux I use arch BTW on my desktop
