i guess if they work better for you.
im not partial to the iLife suite, but iLife 08 came with my computers and i use them from time to time to do some quick youtube videos, a few sound effects and import photos from cameras etc.
also, will those Apps mesh well together? can import directly into or form each app into each other?
thats one advantage iLife seem sot have to be able to work in conjunction with each other etc etc.
However some of the apps have some great publishing to the web features; ie. Picasa.
etc etc,
i know its not a Yes or No answer...but just because theyre free does it make your productivity any better or would you benefit from a suite of apps?
