Why limit yourself to a Chromebook? Macs and Windows PCs have a browser plus everything else. If all you want to do is browse the web a tablet is a better choice.
Windows is just so awful I don’t know where to start haha
ADD: as for cost, in my experience, my MacBooks tend to live for MUCH longer than my winbooks. My wife's MacBook Pro is over 8 years old. Personally I dread switching notebooks (moving data, adding customization, etc) and would happily pay double for something that will last me twice as long or longer.
I'm still delivering software and making money from my Toshiba 1805. I'm not sure exactly how old it is though, I got it secondhand maybe 19-20 years ago.
I also didn't lose much battery life, probably 5% overnight-midday.
