Tinkering with a Kospet ROCK

A few thoughts about the development on this watch:

• I don't really use the web IDE except for the REPL and to deploy files to storage. I'd prefer to use something more streamlined than a platform-specific IDE. Any advice ?
  
• I tend to use a lot of closures in my code, and I'm wondering if the overhead of that coding style is going to be significant enough to be a problem.
  
• A lot of the device-specific stuff feels like copy-pasting magic runes from a more advanced wizard.
