4. Extensible. MC2 is extensible in many aspects, the GUI is based on
OB and the versioning model is simple and can potentially used for
other data than code. Take the example the task of versioning files
together with Smalltalk code. A thing that is nearly impossible in
MC1, though in one of the first versions of MC2 I could implement a
working prototype within half an hour wihtout being exposed to
documentation or the code before.

5. Portability. For me this is one of the most important points. MC2
clearly separates common, platform-dependent and GUI-specific code.
The current implementation of MC hardcodes to many things to easily
port to other Smalltalk dialects (GemStone did the impossible), and
therefore people write their own libraries in VisualWorks, VST, GST
and Dolphin to pull code from Squeak. This is a deadly one-way-road
for open-source projects like Seaside or OB, because people working on
these platforms are unable to contribute back conveniently. I hope
that MC2 will be able to change that.
