A brief history of Celestica
Celestica are one of the big three contract manufacturers including Solectron and Son Hai aka Foxconn.
Cleestica as created in a novel way - IBM built the worlds most advanced and automated plant for manufacturing PCs and made a loss because of the layers of management so sold it - to some of the managers who then started selling the PCs at IBM a good price.
I worked for them in the UK on a range of projects for six years.
