I think I'm about halfway through Mass Effect 2 and I have to say Mordin Solus is my favorite character. Not to say that the other people you run into are slouches but Mordin is a stand out. He talks pretty fast but he's no one trick pony. Check in on him often and you won't regret it. A few things he does left me wondering why there wasn't an "applause" option on the dialogue wheel. Maybe my Commander Shepard is too uptight, or maybe Salarian's don't appreciate it. Either way, when my party rolls into operation Mordin is always riding shotgun. I wish I could say more, but I don't want to ruin the surprise for anyone. 
 
I'm almost curious what he would be like if you piss him off or he doesn't trust you. Maybe on another playthrough, but I don't think I could do that to him.

When he sang, oh my God, was that awesome.

lol when he died my first playthru i imagined a slowmo montage of him singing his salarian professor song and felt really bad. so i totally got him out with the crew the second time

He is the very model of a scientist Salarian.

I agree. He is so far the best character of 2010.

I also love it when he...

The dialogue where Mordin warns you of the dangers of interspecies romance is up there with him singing. He's also probably the most interesting character in a serious aspect as well. His sidequest and the subsequent dialogue concerning the genophage and krogans was some of the best in the game. The way he stopped speaking so quickly in those scenes was such a nice touch by Bioware.
