I had (have) a Nexus S. The hardware at this point is coming up on it's third birthday... yes, it is ridiculously, unapologetically slow... but if you look at the iPhone 4, it's not fairing so well either.
Yes, old hardware will always fare poorly when running operating systems that are generations ahead. Try running Windows 7 on a 286... Nexus 4 and I'm loving it. I anticipate no issues moving between 4.3 and 4.4.
Oh, and I suspect your battery is torched. my wi-fi only nexus s reports on average a solid day of battery with moderate/heavy use.
