You're being generous about it being laziness. I'm blaming my own on old age. :-) But seriously, there are pros and cons with this. On the one hand, by outsourcing certain aspects of memory, we can hold much more. It's kind of like learning to call APIs rather than re-writing everything from scratch. On the other hand, I believe that instant recall has it's advantages. (I think our generation can do math approximations in our head faster than the current generation, and that's an advantage)
