I just shoot pictures; stick the memory card in a reader, copy the files to my hard drive and use Adobe Photoshop CS. Sometime when I have lots of pictures and want to sort them into folders, I use iView Multimedia Pro (Mac OS.) But most of the time I use Photoshop Cs's File Broswer function to look at, rotate (I keep the auto-rotate feature of the 10D off), and open the files. I use Photoshop's RAW conversion too although I hear it's not that great; it's good enuff for me.
I heard that the software with the new EOS Mark II will have the best RAW file conversion of anybody (third-party or otherwise) but Canon has not decided if they will make it available for the RAW files created with the D30-D60-10D family of cameras.
