There was a thread about this a few weeks ago, a bunch of people posted their desktop/monitor layouts. I think most were stretching across both. A search for 'dual monitors' should turn it up. On the obj export: yes. OGL preview is pretty good, particularly with transparent stuff like hair. It actually looks like hair in preview now. Dunno about a single review but you can find dozens of user impressions here, there's a new P6 thread started about every 2 days. Generally the people who are most critical of P6 are the ones who haven't bought it yet.
