Reading this on Kbin.

I think it's hard to gauge when looking back. In Window of Opportunity, Malak has a fold out picture screen; we now have folding smartphones, but looking back you would realise how futuristic that concept would have been in the late-90s/early 2000s.

This shows the Point of Origin symbol for New Lantea. Atlantis moved there from it's original home of Lantea at the beginning of season 4 IIRC.
