installed linux, dual boot, vitual mashine, live cd comparison

installed Linux
-you'll need a PC

dual boot
-less disk space for your Linux partition
-possible problems
-personally i don't like multi partition disks

virtual machine (in non Linux system running Linux)
-slower
-no direct access to your hardware
-problems?

live CD
-slow
-occupied CD ROM tray
-no easy customization

actually i wanted to say for home use you'll need Linux installed
all other ways are
Not a bad way to get your Linux feet wet.
