For those that think the Vivi Nova is a big large there is a vivi nova mini that should be available soon. Several positive reviews are out on it already. I think it's supposed to hold around 2ml and should complement the form factor of the battery much better.
I heard about that.
Vision is starting to make all of their clearos rebuildable. I now see that the stardust is rebuildable. I wonder if si is going to get them.
