16MB is >10x more than Red (batteries included) and also Red takes different approach to GUI - it's platform independent but with OS widgets - so it ages with OS, unlike custom solution.

However, GUI is not the main point of Red, just a part of it. IMO the really special thing is it's ability to create and use dialects (DSLs) very easily, so the 1 MB package can handle tasks from device drivers, through GUI, to natural language processing, with specialized dialects (DSLs).

Unfortunately at the moment Red does not really include a lot of batteries (take a look at IO in their documentation)... Also what's the point of a platform-independent GUI-toolkit if you have to abstract a multitude of different OS-provided-libraries, when you could just use the library as is (which itself is an abstraction over the basic OS-rendering-primitives)?

Also could you elaborate what's so special about an DSL if all of these are locked into a specific syntax (or does the almighty red also include some super-easy grammar-description tools?)
