As I use Bootcamp and Windows Vista from my Macbook Pro and switch between the OS more often, I had a hard time in trying to select the OS which needs to be booted. For example, during reboot/fresh start I need to hold down the option key during the initial time and then I used to select the partition to which I needed to boot. At times this is frustrating as by default it used to boot to Mac OS X if you forgot to press the options key and select the OS to be booted.

Other day I found a solution for this by using rEFIt, a Mac Boot menu. Which allowed me to make this boot menu enabled automatically every time it boots; and good thing is it defaults to the last OS that you booted and it has customized icons which also distinguishes the underlying operating system.
