The Eclipse/NetBeans war is very very old news.
Most of us Sun folk around here are IDE neutral and don't make a big deal out of it. Im using both right now and I see advantages and disadvantages to both.
I think most users are too - even though I'm a 100% eclipse evangelist, I have a suspicion I *might* be about to switch to NB, since eclipse is still failing to fix the massive problems from 12 months ago, and what I'm hearing and seeing of NB is looking tempting enough that it might be worth switching.
Personally, I have zero loyalty to an IDE these days.
I will never *forget* how incredibly stupidly "we can't program for crap" NB has been since the day it was released (possibly until now...that's what I'm yet to find out), but I'll easily forgive and move on without a backwards glance. There never has been a valid excuse for what a stonking piece of crud it was, and I am still bitter at the time and money wasted even personally (let alone by all the contributors) trying to use it - exacerbated because it had caused the close down of other, better, projects, and there was no alternative left.
But ... if it's fixed now, then I'll switch in the blink of an eye, and sing it's praises loud and clear. Shrug. Loyalty, what loyalty?
Then again, Eclipse is, fundamentally, a better idea. This isn't suprising, considering how much expertise and money IBM already had int he IDE space before NB's predecessor even started. But eclipse is now so stagnant and miserable that if NB gives it a kick up the backside, people will switch in droves, IMHO.
As noted above, competition between IBM and Sun seems - to this observer - to be the only thing that keeps java alive and kicking ass, as opposed to getting old and sluggish and sitting in a corner snoozing
