So the pulins on the roof don't sag, they are just 2x4's laying down. the 2x12 beams hold up the trusses between the post's.

Yes, but diagonal bracing from the post's to the beams is required here at least.
Is there any advantage to doing this over trusses 8' oc and purlins on edge?
I would think it would be less economical.

I can't comment on that...

8' OC trusses are usually about double the price of a 4'OC truss. They weigh a lot more too which could make them more difficult to set.
When I built my 30 x 50 barn, a 4'OC W truss was only about 40 bucks each.
I ended up building mine as I wanted a scissor truss for greater toom on the second level, and they wanted over $100 each for them. And they don't use any more material than a standatd W truss??? I only had about $30 each in making them.

You tell me!
I'm in snow country, but feel that with steel roofing and purlins, I'm more able to spread the trusses out as opposed to the weight of plywood/OSB sheeting and asphalt shingles. Plus, the steel roof tend to 'shed' the snowfall. I'll have no doors under the eaves, so it sliding off in piles, doesn't really bother me. I've got a couple PE's at work (Eng & Arch field), and I'll run anything I come up with, by them, as well as the Truss guy! ~Scotty
