Usually, sure. Applies to everyone, though. Quality is a big question mark for everyone right now.
Panasonic has one DVD-R/HDD combo that's more in the price range ($700), but lacks input ports and card slots, rather restricting it to fancy VCR work. Its $1200 version is the one appealing to people wanting to transfer on digital movies and all that jazz, and even the 40GB version of that runs a grand. On the whole, a bit confusing...
No others that I have seen yet offer networking, either. At least not for real networking--some are apt to have for TiVo guide updating and the like. (Also, none seem to play the specific DVD+RW format, either, just -RAM -RW and -R.)
These items are currently expensive, and will no doubt remain so for a while. I figure the PSX might shirk on some of the most advanced video quality features, but it certainly offers the most extraneous other features, as well as more likelyhood of future projects. (PS-playing ability, networking, Linux, and more incentive to play around with computer-type activities than Toshiba and Panasonic and others will have with their players.) Frankly, I figured the PSX was going to cost in the $900-1000 range along with said other players, so I'm glad it's able to come out where it's planning on. Probably trying to jump the gun with the concept and get in not only early on in their lifestyle, but take advantage of price and extra features that would make them a standard purchase for that kind of unit. Certainly not going to be high-volume any time soon even at that price, but they choose an interesting route.
