Updating iTunes software is one of the most avoidable tasks

I don't know about others, but whenever I try to update the iTunes, I get a welcome message with an update size of at least 50MB.Should I call this update??Seriously.To me, update means less than 5MB size only and in this case I have to download the entire software again.What a waste of time.I haven't seen any complaints over this on the internet.May be people are so tolerant to this non-sense.But not me.iTunes is a good software but this kind of bloated updates could drive away loyal users like me.May be Apple should take notice of this and they shouldn't pump more than 5MB size updates.If you see this post by any chance, please share your feelings on this.
