To be honest, I wouldn’t buy a Windows laptop with less than 16GB RAM at this point in time. Modern web browsing is a major memory hog.
As for iPads with 4GB or less, yeah, unless there’s a specific use case with relatively light performance requirements or a need for a certain form factor, I wouldn’t get those either.
16 GB is the bare minimum for a computer nowadays. Though 32 GB is even better if your a gamer or use some VMs.
