And just to build on this point a bit more... The changes referred to in the mail that opened this thread - GTK3 and PyGI - are not expected to be items of bloat. Rather the opposite. Moving to PyGI is expected to reduce startup time and reduce memory usage. No need for me to repeat Tomeu's arguments; http://blog.tomeuvizoso.net/2009/05/reducing-sugars-memory-usage.html This move will also allow us to drop a load of bindings packages, as the way PyGI works is that it allows python to call into C libraries through only a small generic introspection layer, plus a few small introspection data files. That will save some disk space. Moving from GTK2 to GTK3 is not a significant change. The version number bump was mostly for some internal restructuring and backwards-incompatible API changes, the actual end result is not that different from GTK2. Some things are faster and smaller, and GTK3 .so size has dropped 0.2mb to 4.1mb size on my system. A few things might be slightly slower, but the benchmarks I saw indicating this largely blamed the GTK3 theme for the small performance losses (which Sugar won't be using), and you won't notice it. Right now we ship both Mozilla and webkit in our builds. Both steps combined will allow us to drop mozilla, saving 30-50mb of disk space. I'll let others jump in with the "and webkit is faster/better" arguments! Sugar is growing features, but nothing that I feel that challenges the XO-1 at this point. The XO-1 images are big, and Fedora creep from 9-11 and 11-14 has hurt us a little, but we expect XO-1 deployments to ship without GNOME (which several do, at least), so the issue isn't as big as it appears.
