For me the speed in which you can edit and make new charts, as well as drag and drop for playlists etc was well worth the extra money. I was actually using the Android Ireal B version on my Motorola, bought the mac version and finally upgraded to the ipad version. I only use the ipad for editing when I'm either on the gig or on the fly, otherwise the mac version eats it in speed of time and ease of use!

My 2 cents, anyhow!
