Good morning (or day, where ever you are) to all owner of one or more Toughbook(s)! I thought it might be interesting to gather some information about the natural life span of a Toughbook. My CF-18 MK4 now has passed the mark of 8700 hours. When looking for a new Toughbook to buy, operating time always is something to keep in mind. But how long do these things actually last? I'd find it interesting to know, so I suggest we all collect our data to calculate an estimated life span of a respective model. Of course individual cases by themselves tell little about the long term performance of a model, but all our data put together certainly does. So if you find the time, post your operating time of your machine(s) here, and if they go dead edit the post. I would really like to know how much time my machine still has (or could have). Well anyway, thanks for your time and I really hope we can come up with some interesting and useful results!
