I tend to notice every little problem with any type of screen - heck, I fall into the 1% of the population who can see trails on plasma TVs. Yes, I see the interlacing problem, but compared to the 2000 (my friend owns one), I'm glad I got the 3000. Honestly, the problems aren't really that noticeable (the echo of the Internet tends to make it seem worse than it is), but the better refresh rate and more pronounced colors make it better.
But, here's the most important thing - if you don't see any problems when you get it, don't go looking for one! Just enjoy it and be happy with it - when it comes to any type of screen (TV, monitor, etc.), ignorance is always bliss!
