I'm not adding a different opinion on the topic, I also think it depends on the buyer and his or her preferences. In Southern California where I grew up, pools were in high demand. The home I grew up in had a pool, my aunt's home had a pool, my other aunt's home had a pool, I could go on for days. But up here, it's generally not sought after. I personally would not want a pool just because there is too much upkeep for the few, hot, days that I would be able to use it.
However, I wouldn't mind a good compromise! Condo associations with enclosed, community pools. There are also quite a few new developments with single family homes and enclosed, community pools. The more amenities the better when it comes to developments where the buyers pay HOA dues.
