Porting to Other Devices

Directly quoting from the Ubuntu Wiki (obsolete URL removed!):

We want to port Ubuntu Touch to all kinds of devices. If you have experience in porting code to Android devices or are generally knowledgeable in terms of porting, working with the Kernel and other core bits and pieces of a distribution, this might be interesting to you.

Moreover, there's really no way to tell which future devices people will choose to work on, however there is a working list of devices that the community is working to enable here:

Only for Evaluation

Quoting from Ubuntu Wiki (obsolete URL removed!):

The Touch Developer Preview project provides the open source code for enthusiasts and developers, to familiarise themselves with Ubuntu's phone and tablet experience and develop applications on spare devices.

It is currently work in progress and intended for enthusiasts who want to contribute testing and building the platform.
Further quoting from their Install page (obsolete URL removed!):

It does not provide all the features and services of a retail phone and cannot replace your current handset.

This process will delete all data from the device. Restoring Android will not restore this data.

So be sure to do a complete backup before venturing out.
