Point well made!
I got my first dslr around 2000 and have shot RAW ever since. Like you, I have them all on a large disc with a backup. Every new advance in Photoshop, or to be more precise, Adobe Camera RAW, makes looking at these RAW images a new experience. I am currently going through my old images in chronological order looking for suitable candidates for dramatic Black and White conversions. ACR gives me all the tools I need to achieve this.
