i've had the ip35-e for almost a week is all but i can say its a very stable board. im very happy with it. my biggest gripe is the dreaded double boot but i rarely hard reset so its not huge for me. too bad i cant really test the thing out due to having a cheap chip lol. this guy has done a pretty good job at putting a review together for the ip35-e:
