Can you explain why you're getting that & not a laptop with a NLE?
You can get 3 sets of: 17" MacBook Pro, Final Cut Studio & a Matrox MXO2 for the same price.
Every time I look at that HPM200 I just think that is is built for people using P2 (a non-linear shooting format) but want to edit in a linear fashion (ie tape to tape).
I've used some portable Beta SX & DVCPro editors & they were great for editing in the field. But once I started editing on a laptop, I just don't get what the appeal is.
The only thing I see is that they can work like a VTR in the field. So get an I/O expansion for the laptop & turn the laptop into a VTR.
