Google is taking a hard line on the latest version of Android. Honeycomb, it turns out, is not for phones. Asked when a version of Android 3.0 would launch for smartphones after the event, a Google spokesman told the crowd that the last version of the operating system is intended to be tablet-only. “Features will arrive on phones over time,” he told the press.

The answer isn’t entirely surprising. After all, Google insisted that Android 2.2 wasn’t optimized for tablets–not that everyone listened, of course. We saw a number of Android tablets flood the market prior to the soon-to-be unreleased Honeycomb.

Now, such a proclamation raises questions–for starters, what does that mean for the numbering system? Before Honeycomb, every Android upgrade was tailored for smartphones–now that 3.0 is tablet-only?

Google’s in a bit of a precarious position at the moment. The company is still preaching the openness of the software, but it’s beginning to insist on more concrete rules, to help avoid risking further potential fragmentation for the OS.
