I don't regret moving to digital one bit. I'm having lot's more fun.
I'm using a Nikon D200 which is about as good as it gets within reason from my perspective. I won't live long enough to figure out all the menus. Things I miss about 35mm or don't like about digital:
1. Darkroom fun
2. More resolution (I guess you can now get resolution that equals the finest 35mm film cameras, but I believe the cost is prohibitive.
3. Too much learning curve. I won't live long enough to figure out photoshop.
4. Thousands of photos stuck in my computer waiting for me to find the time to "adjust" them.
Things I like about digital:
1. Instant review
2. Upfront cost offset by low continuing cost.
3. Shooting in raw allows me to remake the image later (if I ever find the time to learn Photoshop and adjust all my shots).
So it's a mixed bag. Ten or fifteen years ago, I considered myself kind of high-tech. Now, I find that I am less interested in paying the large price of long and difficult learning curves and complex sequences that once mastered are soon forgotten if not used every day.
Maybe it's an age-perspective kind of thing.
ANyway, the proof is in the pudding. I no longer use film, only digital. It's holding its own.
