Aceflor, just don't let the Glo update if you decide to get one, and for that matter, go back to the firmware you liked for the Aura (which is probably 2.5.1, the one I'm using and will continue to use until they release an update without bugs and without adding things I really dislike).
This thread has links to all the previous firmware versions to download. That way you can enjoy your Aura again and not just have it sitting around hoping for an update that doesn't take away something you enjoyed.
Edit: Yes, I fully realize that criteria may keep me from ever updating the firmware again on my Glo...
