Work laptop

I'm Ela, or Elamimax for those of you who know me through my work online. Recently I had a hardware issue that made me realise that I need to not have all my eggs in one basket. 
Additionally, I think it would also be a good idea to have a way to change my environment in a healthy way while I'm working. 
So I'm looking to purchase the cheapest laptop I can find that still has a somewhat decent wifi adapter. I don't need it to play games, or watch movies. I just need it to type, and maybe be available for voice calls. 
I'm very grateful for the support I've already received from all of my readers, my friends and my family, and i do feel guilty asking you for this. However, with your help, making my living as an author is becoming ever more viable.
