Ask HN: Mobile Device for Casual Coding

Hi HN. Since my daughter was born, my free time is very fragmented. An hour here, half an hour there but no longer periods of time, especially none that can be planned in advance. However, that's fine because my energy levels also don't allow fore more endurance.

I have pretty beefy gaming laptop with Windows, an Android smartphone and an Android mobile phone. The laptop would be fine for coding but I really don't like setting it up. It's very heavy, it does not run very long on battery, the power supply is chunky and heavy and the device and power supply get pretty hot. So what I mostly use are the smartphone and tablet but they suck for coding.

That's why I'm looking for a device that fulfills the following requirements (I'm also very open for other suggestions):

- Price <= 500 Euro (limited budget unfortunately) - Long battery life - (ideally) USB C as power supply - Relatively slim and lightweight - Keyboard - Decent development environment [Linux would be fine] - Web browser - WiFi

The idea is that it's a device that I can just pick up wherever (on the couch, in bed) and whenever I feel like coding something.

What I would like to code on it:

- C/CPP (possibly SDL) - Python scripts - Web (HTML, CSS, JavaScript)

I kind of like the idea of Chromebooks but I'm a little afraid of Googles walled garden and completely depending on their web services.
