Took about an evening of tinkering and reading the TonysMac86 forums (really helpful community) to set up and has been trouble-free since. Sleep/wake works with the lid and it even supports dual batteries. Battery life is good too.
Hackintoshing a laptop is harder than a custom-built desktop as you don't have much choice over the hardware. For example often the internal wifi and bluetooth cards aren't supported - I have to use a USB dongle on mine. However, there's some good resources on TonysMac on which laptops are the most compatible.
