I have Linux on all my servers, was an early (very minor) dev on pre-1 kernel and generally love it.
The desktop is a walking nightmare. Something continuously does not work: multiple screens, waking up from sleep etc.
I really would like to move (we use Outlook but I am even ready to go for OWA) but Windows is considerably better on laptops.
Again, I love Linux and have managed literally thousands of them since 1994.
I'll concede that if you're talking about the trackpad, Linux is disappointingly bad compared to Windows. It's really really shaky, scrolls up and down with a shockingly massive jitter. You start to wonder if the trackpad itself is malfunctioning. Sadly, the same trackpad works so much better on Windows.
This is mainly about the pointer / trackpad drivers to be fair, but it's still a freestanding issue that has the potential to really bug someone using Linux on a laptop. It gets so bad I have to carry around a mouse.
