What is the difference between System Builder and Regular

What is the difference between:

Microsoft Windows Vista 32-Bit Home Premium for System Builders

and

Microsoft Windows Vista Home Premium SP1

Is the main thing that you can only install it on one system and can't use Microsoft for support?

SP1 is better!

you will find if you get the 32 bit version you will / might have problems... so i say SP1

Thanks for the info.
Is it really even worth it to upgrade just yet?
