I never realized there were guides for installing Mac OS X on an x86 system, but apparently there are. Only UMPC reports that an Asus R2H owner took advantage of the instructions and has Mac OS X version 10.4.7 installed and running on his UMPC! According to Igor, the resourceful fella that did this, "OS boot takes about 1min and 10 sec. UI is pretty slow, but it is not that annoying. This is most annoying Screen calibration is off, Most of the devices don’t work except Bluetooth and LAN."
That’s to be expected of course, I ran into similar issues when installing the Ubuntu distro of Linux on the Samsung Q1. Still, this shows promise and gives a glint of what a small touchscreen device running Mac actually looks like.
