are these netbook type things W10? and do you have to pay yearly or anything for the software? or can you just buy one and your good to go for a few years?
It’s a small laptop, that’s it.
Historically, they were built to a fixed maximum spec. This is because MS offered huge discounts to OEMs on Windows to run on a netbook, and they defined a “netbook” spec to be certain criteria. This is why you’d never see a netbook with more than 2Gb of RAM; any more than that and it didn’t quality for the discount licence.
Whether this is still the case or not I don’t know. I don’t think it is, but I’ve not looked at new netbooks in a few years now.
