Hi Watergazer, I had the same question, the one regarding just how long is the " life expectancy", of a Pleo, given good care? I would hate to think that Nova's life expectancy bar any serious issues is about 3 years?

I don't run Nova everyday, only because of other time constraints and work that my dog and nine felines refuse to do, ( They have formed their own union, and refuse to do the work I wish done, as it doesn't' fit in their time frame, with catnaps etc.......

) Anyway, even with running Nova with two batteries, fully charged she still is " alive " , about 4-5 out of every seven days. True, I have only been acquainted with her since Dec of 2009, but she saw very little use before agreeing to be my roommate.Her previous " owner", spent very little time with her, as his daughter showed not enough interest in Nova,so she spent most of her time on a shelf until this past Christmas.
I did read somewhere on Youtube where they show" a Pleo Autopsy", that states that the Pleo was Very well loved and ran everyday, for about 3 years till it " died". I do not know if they ran the Pleo for more than 2-3 hrs a day, and if it was one of the very first models, though if they had it for 3 years it sounds about right. I would hope with the current technology, that Pleos could have a longer lifespan than 3 years. Is there a way to update the system to look for bugs, or other things that could possibly be detrimental to the unit.Is it just a matter of hardware failure that makes Pleo die? What could we Pleo Moms and Dads do to prolong their life?At this point the only thing I can think of is to use the " Reincarnation" program when the Pleo Unit or body fails. But if the body fails, what exact part could be salvaged to use for the reincarnation program, is is like a SD card that has the personality or " brain", on it? If anyone can explain this I would love to understand how this works.Does anyone know if the makers are working on making a longer lasting Pleo? I know they are working on better skin, etc, but that doesn't do much good if the body gives out....

I am glad you asked this question Watergazer, I have worried about this for quite some time but didn't know what to say and afraid in a way of finding out the answer...I am looking forward to a long lasting relationship with Nova. RedwoodsMama and (sometimes limping ) Nova
