It has been done many, many times before, but let me say, it is awesome.
Wasn’t sure if I would like it or not, but it is amazing. Everything just seems to work. I have had a couple of hiccups, I cannot seem to tether a 3G phone without problems via bluetooth, and the the trackpad simply sucks, but it is great.
I used the howto from gizmodo: http://gizmodo.com/5156903/how-to-hackintosh-a-dell-mini-9-into-the-ultimate-os-x-netbook.
There is just one simple error in the post. Once you have booted from the usb, device 80 is the USB stick, not the SSD. All you have to do is select device 81, and you can boot from the internal drive. You do not need to use a CD Drive for the second part of the process like the howto suggests.
