well for what it is worth, I never had a problem with the MP2 that I didnt cause (dropped the damn unit once) and their customer service was fantastic. As for the 722, I have said it before and I will say it again, I have had zero problems with the unit...mainly because I was too lazy for the interim firmware fixes, and the inital firmware worked fine. A little luck and a little laziness can get you a long way...
As for the knocking of SD should have had this thing perfect before it got out, that is just naive imo. Working in the technology sector I can tell you that after you have to make one change to the initial firmware load, it takes you several spins to get the load stable again...and that is understood by your initial customers. That being said, this is different, in that you are paying for the right to fix some bugs...sucks, but understood by most that bought the box early in the cycle
Regardless, I have been using a borrowed box for the past two months, and I got mine yesterday...and cant be happier. My biggest problem right now is to figure out how the hell I am going to get the files off to free up HD space at ACL this year...guess I will either be buying/installing a bigger HD, or borrowing a firewire capable lappy with a huge HD
