Well, they also thought it would be great to have a custom OS for every phone model. They had symbian-based S60 in different variations, S40 (or was it S30) in different configurations, some with Java ME support, some maybe not, and so on. Symbian came with different UIs I think, so some other vendor also had symbian phones that were completely different (was it sony?).

Clusterf...

And then Stephen Flop thought it would be cool to go exclusively with Windows Slown instead of the widely popular Android. (or arguably he was probably paid to decide that, coming directly from MSFT)

I can only imagine how defunct the organization Nokia must have been, with this cornucopia of different phones. Impossible to reform, so the only way for them to go was ... to go.
