Yep, same boat here. We recently upgraded our family plan to 3 EVO 4Gs, (18 yr old daughter, wife, and I) and the 18 yr old asked me about jailbreaking. "It's called rooting, jailbreaking is for iphones." I have one down and 2 to go. I ask them if they want me to flash theirs yet, and I get this wild look of fear in their eyes. They grip their Evos to their bosoms like I was asking to take away very soul. Yet, it is only a matter of time, because as they complain about their battery life, asking where the charger is, I laugh and tell them where my battery is at. They look at me with scorn in their eyes.
I do highly recommend Azreal X as a ROM to try. I'm running 3.1, but they just released 4.0 (ggggrrrrrrrrrrrrr!) yesterday. Yeah, that's right, I'm upset, because I absolutely ADORE my phone's performance on 3.1. They can't make this any better, can they? I see the new features, sigh heavily, and click on the download link.
Oh, BTW, has anyone named theirs yet? Just curious.
