I’ve never had my alarm fail, but it looks like others have hit this bug. So by your definition if a product has a bug (even if rare but intrinsic to the functionality), then it’s half baked. Given (effectively) all software has bugs, then by your definition there are no fully baked software products. I think we have very different definitions of what makes a product half or fully baked.

I haven’t used Books extensively outside of audiobooks. So it sounds like there’s offloading of caching going on that’s iCloud wide; disabling iCloud sync would fix this. I can imagine that being frustrating if the book you want isn’t there when you’re on a flight (which should only happen if you haven’t recently accessed it). I agree there should be a way to prevent this. I wouldn’t call that half baked, but it’s a big enough problem I’d agree that’s not fully thought through (or more likely, they did think through it but came to a different conclusion).
