Android phones, apps and tablets

You mean Nokia right... don't they own the lions share of Symbian?

And they do... hence Nokia and Apple being involved in a legal case of their own.

The real winner is probably Palm, who have a patent arsenal on the older smartphones that could probably take down any of these upstarts.

Palm also look very cheap at the moment.

No-one owns Symbian any more. It's available for free to anyone under the terms of the Eclipse Public License. The Symbian Foundation, an open source software foundation, integrates, releases and promotes the platform.

Palm are dead. I'd be surprised if they are still in business by the end of the year. Their patent portfolio, which isn't that good to be honest, is the only thing of value they have left.
