Free: Contests & Raffles.
This is the link from one of the sellers that doesn't offer the CD. They say it's a free download for the software that comes with it. But then again they're an eBay seller.http://esupport.sony.com/US/perl/swu-list.pl?mdl=DSCW90&LOC=3
Does anyone know if they make a 9v battery "life left" or "% used" device that can be wired in? I always swap out my 9v in my homebrews because I always want fresh batteries in the unit. I suppose you could just carry a batter tester in the field and check them when you're out but that's kind of a bother.
