As Nathan points out, you'll have more control with the SDK, than with IZL.
Of course, your development time for small IZL-capable apps on an OG will
progress much faster than having to take time to learn the SDK.
If you're comfortable with C, and are comfortable programming in Windows(you
didn't say whether you programmed Windows programs) the learning curve for
you may not be as high as it is for someone who hasn't programmed in Windows.
If you're just familiar with the environments, and haven't programmed for
Windows, then your learning curve will be similar to others. Actually, what
you'll find, is that after understanding the GEOS objects, it will be easier
for you to program in GEOS than Windows because a lot of stuff is done for
you. i.e. Windows are managed by a "geometry manager" instead of having to
be manually manipulated and resized by code you'd have to write. You "can"
override the geometry manager, but you do so knowing you'll have to write the
code that it takes to do the same thing. So on average, you probably could
get an application running faster via GEOS' than via Windows' SDK.
