I am currently using Sony TRV 355 and now planning to buy a Sanyo Xacti C-6. The only thing stopping me is that I am used to 20 optical and 700 digital zooms of my Sony. Whereas Xacti has 5 optical and 12 digital zoom. I wonder what shall I be able to do with comparatively so little zooms. I wish to know
1)Is Xacti's zoom sufficient for long range outdoor filming?.
2)Is it easy to transfer videos from Xacti to the computer? I find Sony's Pixela software nearly useless for this purpose.
3) Does Xacti record films on a tape and stills on a memory stick?
4) I find Sanyo camcorders relatively rarely mentioned among other brands on websites. Are Sanyo camcorders not popular among users? If yes,why so?

Thanks
