I use a company Apple laptop, must say it's very solid and robust compared to other leading laptop brands, and I sure appreciate having BSD on there as opposed to the other alternative my employer would have handed me, a windows thing. Don't have to worry about driver configuration issues either, the hardware designed for an OS and driver set. I drive two other screens with it on my desk, nice to have three total screens that work well together. Major softwares in the business/professional world can run on it, for some things there just aren't alternatives yet in the open source world.
Now at home I run GNU/Linux, on the two systems under my desk nvidia and radeon driver issues sometimes a pain. But there are things I have to do for work that just can't run on that platform, so I have to fire up windows 7 under vmware workstation. ew.
