Here's some boring stuff like the partition table. The 16GB of storage breaks down like this:

p1 9GB /home/user/MyDocs
p2 4GB /
p3 2GB /home

When using the build and deployment tools, /opt is the default location for user installed apps, so that allowance has close to doubled from the n900. But remember , on the n900 /opt and python share the 2GB partition with /home through mount bindings, not so on the n950. I posted the dmesg in two parts over here.
