MacMini boot from USB
I'm a developer who wants to port a Windows app to Mac.
I have in mind to buy a MacMini but I want to know if it's possible to boot MacOSX from an USB stick.
I ask this because I need to test my app vs other OS like an old OSX 10.5 or vs future ones(like 10.7 Lion) without removing the HDD or to re-install. I would like also to install other non-Apple OSs into other USB sticks like linux or winXP and boot from it.
Thanks.
Mac OS X (10.6)
