Ask HN: 600 usd coder laptop?

Hello! I am running out of money. And my stuff got destroyed in a flood. I decided to save myself and my startup by coding at night when I arrive home from the office.

I need a laptop ( my room is too small for a desktop ) and I have 21 bitcoin (now about 600 USD ) for now a ThinkPad Edge is winning, but someone has a better idea? No apple please, unless you smuggle one for me, I am in Brazil, and they cost the double here for some reason....

By the way, this is for freelancing. This android browser don't let me edit my text and only allow me to add more text. Stupid thing :(
