Hi Bob;
I agree 100% with you about the rate limiting factor being the JavaScript, but
as you can see, even on an iPad or the last version of iPhone, it's very fast
for a small/medium sized structure. I think this is what surprised us here so
much (not totally sure why, with good LOD implemented, we'd need to render 100K
triangles in real time on a small form factor device). JavaScript
implementation speed in iOS (and more widely other mobile OSs) has improved by
leaps and bounds.
As to which is better, iOS or Android-based tablets, I'll pass commenting on.
What I can say is that in my personal experience, Android is a painfully
fragmented platform to develop for, but that to a large extent depends on the
kind of app (BTW, ChemDoodle is a proprietary library not an open source
application like the WebGL described).
Cheers
Greg.

That's pretty much called ChemDoodle. It's not the WebGL, it's the JavaScript
that has to run it that is pretty low power. I have yet to see a large protein
rendered well, and so far I have not seen 100,000 triangles for a surface
rendered at all. My plan is to leave that to others. Frankly, I'll be amazed
if Apple can survive the competition to their iPad. Flat out, the Android
tablet I have goes way beyond the iPad in its capabilities and interface (and
friendliness to developers), and I cannot imagine why one would ever spend so
much money for an iPad these days.

I saw the notice about Jmol running on Android, which is great news. Wanted to
mention that for us mobile device folks, WebGL is also moving forward, and
could be a solution for browser-based mol viz on iOS. I wonder whether
server-side WebGL and Jmol could be mated in some way - or perhaps a pure Jmol
port? I've uploaded a couple of brief vids of one such WebGL app/web page
created by a Japanese researcher, Dr. Takanori Nakane (Kyoto University),
running on an iPad2 and iPhone4 in a web browser app that has WebGL enabled
(it's currently not enabled by default on iOS). The WebGL app runs very fast
indeed:
