Hi Joost, No, i dont think that you are the only one eagerly awaiting an update! But i think that the chances of any further updates for the Equinox series are very unlikely to say the least.
Quite a shame, as with a reliable operating system this could be something extra special.
I have owned my (new) equinox 61 for just over a year now and it has been collecting dust in the spare room for around 9 months as it is just so unreliable and temperamental to take out on the road.
Not one of my wisest of purchases.
