Again, individual experiences vary and this is not my experience.
What does it mean when a company buys a few dozen macbooks, but has zero mac experience and when they fail they end up in a drawer because no one knows how to fix them?
To me this screams "poor planning". When the lenovo's failed they were sent to the in-house tech team, usually they were simply reimaged and put back into production. One of the macbooks sat in a desk for ~8 months due to some "boot issue".
If it boils down to "taste" and your entire company is based on Lenovo laptop/desktops then moving to a mac would seem odd. Again more odd once you realize you cant support them.
