Many may be wondering what is going to break if you make the jump. The good news is that both Lablink and www.weddingprints.com(with Firefox) work. Many of the 3rd party software companies have not released compatible software, IE Nikon Capture NX2, View NX. Also Adobe will only be supporting CS4 for Snow Leopard. If you have an older version, time to upgrade. I think patches for 10.6 will start showing up by November. I will post what I can find as it becomes available.
