+1 for Pixar, -1 for NeXT. You come out even.
Financially NeXT was a wash, the $400 million paid for it was enough to pay back most of the investors, so they got their money back but no profit. For Apple, having the NeXT talent and what became OSX, it was a success for them. So NeXT had value - it was not a "-1" as a company going bankrupt would be.
And if a web startup sold to Google at essentially no profit when you paid out the investors, and the technologies pioneered at it went on to power almost every major product Google released for the following 15 years, people would consider it a deeply influential and successful company.
People seem to grade NeXT on a very, very steep curve.
