Mistakes?
But the company also made some major mistakes. It [..] wasted time and money writing for IBM's ill-fated OS/2 operating system, spent more developing the Notes email system..
I don't think you can punish Lotus for developing for OS/2. At the time, it made business sense. e.g. didn't some of the banks run OS/2 internally?
And I don't believe Notes (More than an email system, as others have mentioned) was a flop. Sure, it didn't stand a chance once MS parked their tank on the lawn, but it was widely used at the time,
Biting the hand that feeds IT
