yeah, like 5 years ago, have you been camera shopping lately?
I have been shopping for a camera just about 4 months ago.
My choice was the Canon HV30. I have read a lot of reviews, most of them said it is the best consumer camera available. This is a tape based HDV camcorder, it has USB but movies can only be transfered using FireWire, USB is just for still images or firmware updates.
I had a look at AVCHD (hd or sd card based) camcorders. At that time there was only one camcorder, also a canon, sd card based, that could match the HV30 in performance, nut not in handling (no viewfinder, just a monitor). If you look at semi pro cameras, they still are all tape based with FW.
But there is another important thing: When I decided for that camera, Apple did not even support AVCHD camcorders! If I had bought the USB based SD Card camera, I had been forced to use Windows software or third party software for conversion. 4 Months ago the only option to work with a HD camera on a Mac was tape based, now they say "trash it and get something else?". Even today Apple does not support AVCHD very well. If you want to import an hour from a tape based device, it takes an hour and a few minutes to rewind the tape. While rewinding may not have a lot of sex appeal today, converting an hour of AVCHD recordings to an editable format takes several hours even on modern Macs. While several Windows programs can edit AVCHD natively without conversions, Apple has yet failed to offer this. They are forcing us to use a system that they don't support well.
Most tape based HD camcorders are also able to output a HD recording in standard DV resolution, which is very useful for previews or quick test edits on the go using a lower speced notebook.
So if you are a "serious" amateur and want a real camera to work with and not just a toy, it still makes a lot of sense to use a tape based one with FW. Maybe you want to get a used semi-pro instead of a new consumer camera? This can be a very interesting option, but w/o FireWire you are locked out.
At the moment this does not hurt me very much, I have a 2.8 GHz 24'' iMac which is very suitable for video editing in HD. But it may be a problem in the future.
