Just noticed http://blog.canonical.com/?p=74 - "For now, builds will expect a minimum of an ARMv5 instruction set". Interesting.

Just to clarify especulations, this is not a covered approach of Ubuntu to Maemo. ARM and Ubuntu have probably good reasons to sign such agreement without needing to put Maemo in the equation. Of course the fact that Ubuntu goes ARM puts it closer to Maemo but that's it.

Note also that the announcement actually talks about "Full Ubuntu Desktop Experience" while "Ubuntu Mobile" is not mentioned. Probably for a reason?

As a note aside, personally I'm looking forward to the outcome of this announcement also for some reasons that hopefully will make our life easier: the ARM stakeholders getting more and more sensitive about open source and the Ubuntu fans learning more and more about why direct comparisons between ARM/mobile and x86/PC are not always applicable.
