I like the idea of music as being an important creative outlet.  I'd like to tie my music into my current emotions and experiences, so that it serves as sort of a diary, but I can never figure out how established artists seem to do this.  For example, I live in the woods, and a fog rolls in. How do I translate that into a synth? Or finish a song before the fog is gone? Is that something artists even try to do?

I'd only upgrade my software if there's a must have feature, or to utilize more processing power.

Other wise it's kind of a wash. These programs are going to have a hard time building on them selves outside of running more efficiently.

That's with any technology though.

I'd say it's worth it to upgrade every now and again if you have the funds, but meh.
