It was marketable when NiMH batteries weren't nearly as good as Eneloops.

If I had to ship my laptop to Apple and pay them $200, I'd be tempted to 
replace it, too.  Should I throw my 3-year-old laptop in the trash?  If 
I spent the money for a laptop, I'd want to keep it to get online in a 
power failure or have files available where there was no outlet.

I wouldn't have bought one.

Why do you think I'm forgetting that?  I believe a Macbook Pro battery 
weighs 24 ounces and holds 60 watt hours.  Six Eneloops weigh 6 ounces 
and hold about 7 watt hours.

Battery life would matter if you spent all day computing in lecture 
halls, but the laptops I've seen used were close to outlets.

Battery type matters if I want to be ready for a power failure. 
Eneloops can sit ready on the shelf for years.  If I run them down, I 
swap and keep right on using my computer by the fire while the other 
batteries charge in the car.
