I haven't been able to find anything on apple being there yet, but the list of sponsors at the GEF is impressive to say the least.

But I am still looking throught both GSF and GEF.

Having the GEF at the same show is awesome for poet, these are the end users so to speak, so they get to talk to a lot of car manufactures ( for example) at one place and being able to say that we are a sponsor at the GSF show will ad a lot of credibillity I think.

here is a link to the GEF site.
