to me the pdaudio thing just seems impractical...too much going on there. I like the idea of the sd722 and was looking at it and planning on buying one someday. however, last i knew the msrp was way above the $2000 they originally said. things might have changed now, i haven't been following, its summer and message boards take back burner when theres stuff to do outside.
I guess if i'm dropping $2k on something i want it to be something great. The sd722 definitely looks like it will be something great, however, from the looks of it, this thing can do everything a laptop can do and fit into the cargo pocket of my pants...or my crotch for that matter. the sd722 can't do that...easily.
Not to mention, when i'm on the road i can use it to check my email and not have to bring along my laptop. it seems pretty multifuctional. when travelling i could watch movies on it. hook it up to the tv and stream movies. hook it up to the stereo and play mp3s, flac's, whatever. all the versatility of a laptop and so much more.
i guess i'm looking at it as more than just a recorder. it has all these other functions plus it can record just as well as any hdd recorder and is far smaller than the others.
*shrug*
technology does nothing but come down in price, and i'm pretty sure that when more manufacturers are making these they'll be down below the $2k mark in no time.
