I picked up a 3000 a few days ago, and i'm glad i went for it over the 2000.
I asked to try both in the shop before i bought them, and the 3000 had a noticeably better screen, barely any ghosting or much interlacing at all and brilliant colours. In fact I was slightly shocked at how bad the ghosting was on the 2000

.
If you're still unsure, ask to have a try of both before you make your decision.
I found the colours to be richer on the 3000 than the 2000, other than that the only differences are the built in microphone and the edges are slightly more curved so it's slightly nicer to hold I find, oh and also it supposedly has an anti-glare coating so you can see the screen better in bright light.
The only annoyance I have with mine is that theres a tiny spec of dust underneath/inside the screen that I can't get rid of

.
Oh, and make sure you get a screen protector, the screens scratch very easily!
Edit: Spaced it out a bit, wall of text not nice to read.
