I don't have time to tinker with compiling kernels, configuring X11, figuring out which photo management software to use, setting up reliable backups, getting my Bluetooth headset to work, and, yes, getting the machine to suspend when I close the lid and wake up when I open it.
These are basics that will just work with OS X, very, very, reliably.
That said, if anyone can point me to a Linux distro (Debian/Ubuntu preferred) and hardware that actually work reliably together, please do.
