Ask HN: Which laptop is best for writing?

For the past year or so I’ve had a lot of ideas for blog posts/articles but never seem to have the time to sit down and flesh them out. Between client work, family time and house maintenance there’s just so many hours and so much energy to go around.

However, I do have two 25-minute holes in my schedule a day - sitting on a commuter train. I’ve been using this time to space out and/or listen to podcasts, but could easily use it to write instead.

Here’s the problem though - opening up the laptop (which belongs to the client) takes me straight into job-mode, knocking me out of any flow I might’ve had.

I’m therefore looking for a laptop that’s:

A) light B) good keyboard C) fairly inexpensive

It seems like an impossible trifecta. Prove me wrong?
