I've been in the computer 'game' for over 30 years, previously as an ex hardware designer of IBM laptops (when they were being manufactured in Scotland!)
If your needs are not too performance orientated (and mainly involve browsing, Youtube, Office, with some light video editing thrown in etc) then the same can be easily achieved for about 200 quid!
For example, amongst the equipment I run I have a 3 year old Lenovo Thinkpad T480, 16GB memory, 480GB SSD with an 8th gen i5, with two! internal batteries, and Windows 11 and it's absolutely brilliant, extremely rugged and bulletproof reliable. You don't recessarily need either an i9 or an i7. This one has been around the world and been kicked about but still looks like new.
At the end of the day it only really depends on which OS universe you're used to working in and how deep your pockets are..
