I would stay with EABI. For one thing I am the kinda "need for speed" user. So it is hard for me to let my Z go back to slower way.
There are two solutions to the broken packages in EABI:
1) Report this to the relevant place (mailing list?)
2) Make our own packages (set up a custom feed)
AFAIK building under EABI is way faster than under OABI, so I suppose rebuilding is not so undoable.
Even though most ARM packages work, but not all work so perfectly. It seems resource taxing programs, like gimp, games, audio-visual apps, may run a bit sluggishly in OABI.
And the others?
