How can you tell what’s hot at a conference? Come to the party and check out the size of the crowds around the tables.

Answer: Android. Android is Google’s open source cell phone operating system and range of cell phones.

Look at TechMeme. The demos are awesome. Go watch them on the Android Community website. They were filmed by this guy who tells me what his favorite demo was.

It’s becoming clear I was wrong about Android (when it first came out I was skeptical). They have one huge hurdle to execute on, though: getting devices into stores so normal people will be interested.

But look at the tables. Android has the attention of developers. That’s key.
