My kids are very young and there are three of them. I struggle to find time when my brain's not already totally fried to finish even simple 1-2 hour projects, let alone re-housing a laptop to be kid proof and fiddling to get DOS drivers working on it, as much fun as that kind of thing might have been to 5-years-ago-me. This many kids+full-time work is roughly equivalent to having a 90-hour-a-week job. I'd rather pay for a finished product—otherwise it'll never happen, and if I try I'll just have a mess somewhere in the house that I'll fiddle with for 30 minutes every few weeks, never making progress. Gotta pick my battles.
