. . . I see pretty much what I've been telling folks for years. 
In our climate (Houston, TX) single pane windows are the best solution. 
Energy savings with low-e insulated glass are pretty inconsequential.

That being said, I *do* like to use insulated glass for acoustical reasons, 
and often suggest it for larger windows when you are sitting up against it, 
to eliminate the feeling of drafty cold 'seeping in'. But that doesn't
happen 
very often here :)

I have also used low e glass on large south/west facing windows. 

But hey, I also tell folks down here not to worry about the r-value of their

walls-it's the ceiling insulation that you need in our climate. If you only 
had x dollars to spend, I'd wager you are better off putting ALL into 
ceiling/attic insulation in this climate.

PS- Obviously I advocate proper site orientation, overhangs, passive
cooling, 
cross ventilation, etc. This I think is where we get the big payback, both
in 
energy savings and Quality of Life.
