What's strange is that the very first impression I got from this is that it's OSS - and it's not - which doesn't make it particularly attractive for me as an 'alternative'. Anyone else feel this way?
It is mostly OSS and can easily be used as a pure OSS solution (perhaps minus some blob drivers from the device manufacturer, but that is true of most Linux distributions with much hardware support). There are some extra features available which require a license, but those are optional and you have to actively acquire a license if you want them.
The main features which require a license are:
* Android emulation
* Predictive text
* Microsoft Exchange support in the email application
