I grabbed the Evo 3D a few days after launch (even though I was not yet due a full upgrade from my Evo4G and had to pay for most of the phone) and have not been nearly as disappointed as some people seem to be. Of course, I'm not stock, so I have no idea how the stock experience is fairing on the 3vo.
As much as this phone appeals to me, the replacement of the Tegra3 means that I'm probably going to pass on this one. Going with the Snapdragon instead of the Tegra2 on the 3vo has really been the only thing that cause me and disappointment about the phone (I even like playing with the 3D camera), since there are great games I play on my tablet that I can't play on my phone. Not really a flaw with the 3vo, but it would be nice to be able to play those same games.
