I'm in the market for a HD camcorder to upgrade my Sony HC90 (very nice little SD miniDV). Typically I shoot ~3 hrs of video on a week vacation then edit it down to 60 minutes or less in iMovie to get the best quality for iDVD burning. I work off of a 2.1Ghz MacBook Pro with 3GB ram and have a 500GB FW800 external. I've read for the best video quality, tape is still the way to go and AVCHD (though improved) still has more artifacts than miniDV. Any reason to jump on the AVCHD wagon or stick with tape for now?
