While that might seem true, it's interesting how the web scene has played out.

When the iPod came out, there was an ecosystem of iPod-related websites that emerged that was distinct from the Apple/Mac web.

When the iPhone came out, another entire ecosystem developed. iPhone-specific sites. The existing iPod sites weren't the ones to gain popularity.

The iPad, however, didn't spawn a significant iPad-specific ecosystem of websites. Instead, it was absorbed within the Apple/iPhone sites, for whatever reason. As a result, I think iPad coverage is harder to come by and is a bit more mixed with everything else.
