With most electronics, if they are going to fail, they fail within the first few months of their life, which is why products usually carry a warranty. I'd rather it fail right away when its within the warranty period then a year from now when the warranty period is done (for non-RRoD problems).
What you don't know is whether or not the RRoD in this case was caused by the same systemic failure of the ball solder separating the GPU from the motherboard due to overheating / heat cycling and motherboard warping which caused the massive failures on the original Xenon boards, or if this is an isolated problem - lets say of improper application of solder for the GPU or a even a bad GPU.
The 3-segment RRoD only indicates a general hardware problem. General hardware problem could mean anything! And we don't know for sure that HarryBallzonya's problem was a 3-segment RRoD.
If 4-segments were flashing, then it indicates the A/V cable was not connected (maybe it accidentally got pulled loose which is why unplugging everything and plugging it back in fixed it?).
I'm not saying that Jasper is for sure fine, but I'm also not saying RRoD is going to plague the Jaspers. I wouldn't worry just yet, we'll see as time goes on. One thing for sure is that less heat production, and less power usage couldn't be a bad thing for any electronics device (except for maybe a space heater)
