#2>Maps render at a super high framerate
You might want to use a nice HTML5 video instead of a .gif, then. It didn't make for a good first impression.
Re: Introducing Mapbox GL
#3This is really cool. It seems that instead of using mipmaps to generate a map, they are using a combination of curves and 2D shapes. This is very smart since the data is not only more compact but can also be visualised in a very fluid manner. The bottleneck is now the GPU instead of the data connection. Give me the ability to download a city's map on Android and I'm dropping google maps like a brick.

#4I played around with the demo map and the scrolling was indeed super quick, along with zoom level changes. If they could do the same thing with WebGL so that we'd have vector maps in the browser (like Google maps) that would be awesome. The competition would be good for everyone.

If you're talking about the demo map in the blog post, you just played with the WebGL version :)

There's plenty of apps on Android that use downloaded maps.

Unfortunately AFAIK most of them are missing many of the things that makes Google maps useful. Real time traffic data, real time road closure data, updated public transportation schedules and closures, search by something other than address, ...
Also I believe online vector based maps teams found that vector map data was actually larger than tiled map data. I thought as you did lines = smaller but lines + colors + line weights + building outlines + elevation contours + street names + road direction info etc adds up were as jpeg tiles can be pretty lossy.

#7Hard coded compiler version?
Could not find compiler set in environment variable CC:
gcc-4.8.
ln -s /usr/bin/gcc ~/bin/gcc-4.8
ln -s /usr/bin/g++ ~/bin/g++-4.8
Also need to make sure python means python2.

#8So this is only for iOS? Is there one for the web?

More details here would be great! Seems like a souped-up version of Leaflet.
Man I love the stuff that MapBox puts out. High quality.

#10I've wanted to write a GLES 2 map renderer for ages -- ever since I saw that the Apple Maps app on iOS uses MSAA for antialiasing (yuck!).
It's funny to see all the usual 2D suspects in the source (clipper, GLU tessellator). They used a distance-based edge shader for antialiasing, so it should look much better than MSAA.
I'm not sure why there's a bias factor of 2 in the "raster" fragment shader -- looks like it might have been added by accident. It's interesting that they use both the stencil and depth buffers for clipping -- I hope they do a write up on some of the techniques they developed!
