The XBR1 behaves that way because it's based on now two year old tech likely. The A2000 is in the comparable timeframe to the XBR2 (not the XBR1) that's what it should be compared to. They obviously had the ability to do 1920x1080 for the A2000s over VGA, but chose not to. I don't care how you slice it... it's crippling. Again, entirely their right to do that. And yes, the HDMIs are there, but the HDMIs all have overscan, vs the VGA ports which are 1 to 1. Also, VERY few laptops (what I'd be using with it) have DVI outputs (on the PC side anyway), and currently there are no VGA->HDMI cables that I know of, short of an external converter box.
No Samsung LCD I know of (nor any from other brands) have glass screens. That's why I'm going after LCD, because it provides no SSE, along with no glare. I sit 11-12' from my 60" and still easily see SSE all the time. Some of us are just unfortunate in that we can't "see past it" the way others seem to be able to.
Granted, prices will of course go down on the new SXRD sets. However, Sony's "everyman" line is the E2000 in reality. I don't think anyone can dispute that.
