Just how involved is Google on the Nexus?

HTC: Nexus One

Samsung: Nexus S

Samsung: Galaxy Nexus

Most people would agree that overall, HTC did the best job on designing a Nexus device. In fact, many hope for HTC to be the maker of the next. Or at the very least, some other OEM entirely.

Why?

Because many feel that Samsung has skimped on the Nexus device in favor of its own devices. And it's hard not to see why many find truth in that. The S2 had a better camera. And the S3 had a slightly better screen, better camera and better internals. (the shell of the actual phone is up for debate.)

This had lead me to wonder just how much say Google has in the whole Nexus process.

From the outside looking in, it's almost as if Google simply draws an OEM from a hat, gives them the software, tells them what the reference CPU will be, usually not the best, but very capable, and then they call it a day.

Granted, Google isn't a hardware company at heart, but it does make you wonder why the Nexus isn't as cutting edge as it could be. Or at the very least, more on level with the other devices.

What do you guys think? Should Google be more hands on and really push for a truly worthy device, or continue to run a middle of the road type of device?
