The 708E is kinda big, considering the camcorders we've reviewed before, but I guess that comes with being a DVD camcorder. But since the DVD part comes right where your handgrip is, it gets a bit uncomfortable to hold for long periods. Not something that's a big issue though, but it still needs to be mentioned.
The thing about Sony handycams is that the interface is pretty much identical in all their models, and the same applies here. There's the trusty touchscreen interface that manages to pack in a lot more than most other uncomfortable button interfaces that I've seen in mid-range camcorders. You can use the interface for just about every function of the camera and it feels a lot more natural too than using something hidden behind the screen flap.
