There are certainly things I can do on my new laptop that was a major hassle on the old one, but web browsing, Python development and day to day sys admin stuff was perfectly fine on the old machine.
For me it's all about the screen, an 11 year old ThinkPad most certainly have a terrible screen (it might not, but most do). Getting a clear hi-dpi monitor is more important than having the latest CPU, GPU or 32GB of RAM, at least for my needs.
