I actually did the same, but I'm back into American Movil (AMX) at $50.00, which between it and NTDOY have more than doubled my portfolio in two years.
The good thing about NTDOY, it appears to be less impacted by the economics hurting everything else.
The bad thing, because of its astounding growth over the past 2-3 years, it is held at a very high level of expectation.
Any bump in the momentum will be seen as very bad, and I'm concerned that their fall / winter product line-up is not as strong as last winter, which featured the Wii Fit, Super Smash Brothers Brawl and then Mario Kart Wii.
I'm not so sure they'll role through this holiday season with the momentum they had last year.
