I have been keeping my eye on this feild for a few years now. I would definantly stay away from Pinnical(previously Miro) boards unless you like the pain of editing for 1 hour then have some kind of a glitch that then takes days to figure out and then days more to reconfigure/reinstall/format reinstall againg and againg and againg so on....
I am very confident that Canopus is rock solid. Just like there moto says "just edit". I do not have any real life experiance with any board but as I said, I have been reading/participating in many message boards for the last few years and the results are allways the same. BUY A CANOPUS
if you can afford it(aprox. $2000/$2500 usd). They do have a slimed down board or 2 for the smaller budgets.
I think that there is not enough demand for these products to be fully digested by Tom and team. BUT.... look at the new low end Mac and PC machines that are coming bundled with some kind of video editing capability. Then take a look at the ever expanding internet use. Then take a look at the ever growing broad band coverage. I truly believe that average person will be using the net for free,quality video phone calls via a capture card in the not so distant future. Then the home edited movie will become as common as the family photo album. All of this means that Tom will (by default) include these products in his teams testing.
Just my teribly spelled opinion
Mark B. "just edit"
