The tech of 1999 is certainly underestimated today
Still, in 1999 I had a PII 333MHz and 10GB HD (and Windows 98, sigh)
But reading about the history of Pixar, the difficulties (in the first Toy Story) involved the workflow of creating a full-feature film (apart from all the other problems they had)
So I'm guessing, since Toy Story 2 was their 3rd feature film, things were still a bit raw (especially given their fast pace)
How is that underestimated, a world of 10GB Hardrives when that's much less than the base package of dropbox these days. Managing the terabytes of data required for the movie back then was a much more difficult task.
