I've been loving the D40 so far. It's helped me realize that I have a lot of rust on my photography hinges. I'm not used to all the features. My last SLR that I used was a Pentax K1000 (still have it too)...needless to say, I'm used to all manual cameras, so I'm not all that used to things like white balance and such.
I've been playing with the Aperture trial since I'm only running OS X. Yeah, I definitely would have to use my laptop for any heavy duty stuff. But for quick viewing and minor adjustments, it works very well.
Thanks for all the responses so far!
One other question: Any particular case recommendations for the camera, that could also perhaps fit the Mini 9? I've got an el-cheapo case that I'm not fond of, but it works for the moment.
