Basically whether you upgrade to have iLife depends on what you want to do on your computer. iLife gives you many features in organizing/editing photos, creating/editing music, building/hosting websites, creating/editing DVD's and movies, etc. Check on the Apple home page, they give you tutorials on iLife, which might help you decide if it's worth the upgrade for you. For me it was the whole reason I bought Mac instead of PC, so iLife is very important to me.
