I've been looking at HD camcorders. I was getting close to ordering one until I looked into what it takes to edit it. Now I'm not so sure. On the other hand, I hate to keep shooting SD video in an HD age. Once you get used to an HD picture, SD just looks so bad.
For SD camcorders, my favorite new feature is the ability to tapeless. I've always hated working with tape. Now they have some that record onto hard disks. The thought of being able to capture an entire vacation without having to change tapes, clean heads, etc is quite appealing to me.
