Does anyone have experience with the ARCHOS 101 Internet Tablet 8gb or 16gb.
Can I install Ubuntu 11.04 on it?
Can I dual boot Ubuntu / Android?
Support for the Archos 101 Internet Tablet in Ubuntu is a work-in-progress. The wiki page describing the current state of these efforts is at https://wiki.ubuntu.com/ARM/OMAP/Archos101it
Note that due to the relatively low memory available for this device, support is never expected to be wonderful: those who do not currently own such a device would be better served by something with a bit more RAM (Archos's G9 series is one example).
Users who have installed Ubuntu on devices with 4GB or 8GB of local storage have expressed a sense of confinement in terms of available storage for common data: while the environment works, devices with 16GB of local storage have received more positive reviews.
You will not be able to use Unity in Ubuntu 11.04 on this device: Unity support for GLES is too new: while it is hoped that it can be included in Ubuntu 11.10, this has not yet been confirmed.
I am not personally familiar with the bootloader configuration for the Archos tablets, but people with similar devices have reported that dual-booting is difficult. In the special circumstance of dual-booting between Android and Ubuntu, you will want to have completely different areas of storage used for each system, which will expand your storage requirements.
