Experience with Mach2 Music Server?

Do I need to can the MM '09 to upgrade to the 2010 unit because it is so much better?

I'm also curious about this question. The 2010 is faster, it can address more RAM and it is easier to install RAM in. But with the internal power supply, does it sound even as good as the older version? I've read mixed opinions on this.

Tvad, I access my Mini from a MBP via screen sharing and I never have to re-enter a password, at least not that I recall.

I should say that my impression is that opinions are mixed. I know there was a thread on some forum in which everyone was touting the superiority of the 2010, but I know I saw some "not so fast" comments somewhere else. I have a aftermarket linear power supply feeding my 2008-2009 model, so I have some skin in this game. I believe it's definitely true that the 2010 is physically quieter, but does it sound as good serving up the music?

A friend of mine uses a 2010 Mini in his system. We're going to do a comparison sometime soon and I'll report back.

SInce they adjust or disable some of the software that comes on a Mac Mini, I'm curious to know what happens with Software Update. Are you able to do updates, including to the OS, without screwing up theMach2 optimizations? what happens at the next major release of OSX?
