Usable it is, fun, not so sure. In a desperate effort to keep rootfs "clean" and spacey in wait for PR 1.2 , I have yet to install anything new since the last minor update. Not only that, I have also removed almost all my apps in an effort to conserve space, resulting in a mere 39MB of free rootfs. I m aware that it usually needs about 42-3MB in rootfs and I have reasons to believe this update won't be any different=/ (there used to be something about it around the forums if you look hard enough).
