Tell me about it(!). I can't play MW2 for longer than an hour online because of the lag - I just end up rage-quitting. When I die on MW2 and I watch the killcam, I notice all kinds of crap that didn't even happen. I think the biggest annoyance is when I run round a corner into safety and still die, but because of the high latency, according to the killcam, I hadn't even made it round the corner when some chap with akimbo 1887 snipes me from across the map (have they been patched yet by the way?)
I know I've already mentioned CoD4 for PC, but when I die I on that I normally end up thinking something along the lines of "FFFFUUUUU-- oh, wait, I guess that's pretty legit. My bad!" I hate how modern gaming is going the route of peer to peer multiplayer; I'm sticking with older games which use dedicated servers for as long as I can. Bravo to Dice for using dedicated servers for the PC version of Bad Company 2.
Edit: You can check out a quick video walkthrough of the maps (recorded by SeaNanners) in the video below. I'm definitely not getting the Stimulus Package map pack now - the name alone was enough to put me off but the only map I actually like the look of is the first one shown in the clip:
