I think that Alan is right in his suggestion that we make amd64 images default before the next LTS.
I think the hardware out there that won't support amd64 is small and like our desktop and applications we need to move forward and not stay in the past.

It would probably be a good idea to get a 64 bit by default release out prior to the 14.04 LTS. > > Alan. > > On 16/04/12 07:03, Steve Langasek wrote: >> >> Hi folks, >> >> Back at last UDS in November, we discussed whether it was time to switch to >> presenting 64-bit images as the default image for desktop, like they already >> are for server, now that all new desktop hardware is 64-bit and multiarch is >> a reality. >> >> There was a rough consensus at UDS that the blockers were solved, but that >> the question should be taken to ubuntu-devel to gather more input.
