I don't know how the data works out for this, but I imagine that SSDs in laptops fail a lot less often than spinners do. "Enterprise use" is the perfect place for rotating storage: the machines aren't dropped off desks, they aren't power-cycled very often, and they aren't stuffed into backpacks while turned on (nearly causing a fire). SSDs don't care much about these things, while spinning disks do. So I imagine that if you have an SSD in your laptop, you are less likely to experience drive failure.

(Another nice thing: those new micro-SATA SSDs are small enough that you can conceivably RAID-1 them in a tiny laptop!)
