Why does everyone hate city living?

I don't dislike City Living at all. Lots of benefits as other posters above can attest. The only downsides to me are 1) Lack of ethnic diversity as other have mentioned. 2) Massive lag I experienced while living on the big penthouse lot (older computer here). My original apartment was three stories with rooftop lounge/dance floor and swimming pool -- a bit too ambitious. Once I wiped it all out and stuck with a more modest layout the lag improved. 3) My sims would take forever to sleep through the night because the clock would slow down to a crawl even on high speed. I assumed this was because there were always other sims wandering around the streets below.
