- iLife integration is pretty darned impressive, particularly iPhoto integration.
- Suppose you want to link to a local file. Click create link, then choose the file. iLife copies the file to its store and creates a local reference. Elegant.
- Fixed width pages.
- Does it ever empty out its database store? I opened the package and found lots of unreferenced stuff from deleted pages. Maybe there's a garbage collection? This could get ugly.
- No importing of existing web pages.
- You can't switch templates. The template you start with is the template you live with. (And this is a database driven application?!)
- Template customization is insanely hard.
- Your work is stored in a proprietary data structure. You can't migrate your work easily to other environments.
 Documentation is to software as facial symmetry is to humans. It's costly to do and has no obvious immediate survival advantages -- so it's a marker for an optimal genome that can afford to "splurge" on hard to do things. Hence the value in mate selection, or so the evolutionary biologists claim. The pathetic state of Sandvox documentation tells me that, no matter how good it may be, it lacks the capital to compete and survive.
