Yahoo! has an article about HD camcorders, and they point out a couple interesting things. Like the fact that buying an HD camcorder is still an expensive affair. And the fact that editing video requires a beafier computer:

You need a powerful computer with plenty of memory to deal with this extra data and compression. For example, Pinnacle recommends a minimum of 512MB of system memory and a graphics card with 128MB of RAM for standard-resolution video, but that goes up to 1GB of system memory and a 256MB graphics card for working with 1080i HD video. That’s a minimum requirement–the more memory, the merrier.

Luckily there is plenty of software to edit HD video. But what are you going to do when you’re done editing your video? You can watch it back on your computer, sure. Or if you find some way to transfer it to a DVHS HD tape, then you got it made. But who has a DVHS player? You’ll have to wait for BD and HD DVD recorders and players to hit the market before your lovely vacation in Bermuda can be shown off in HD on your HDTV. But wait - there is another option. There are a couple DVD players out there than can play HD from normal DVD’s, stored in the WM9 format. But this will also probably end up being a solution just for yourself. Not many people have those compatible players.
