I've had a lot of grief with my iPhone 4. Let's see, 1. Shitty antenna - compensated with free case 2. Lack of free upgrades (Siri, maps) 3. Corrupted iPhone database meant I couldn't copy songs to my iPhone. Had to rebuild the phone to "recover" 4. All upgrades usually take me 1/2 a day to rebuild my phone, as everything is copied off and then back on. 5. Shitty iTunes that makes everything a bitch to get on/off my phone (see 3. Above). My wife has had almost no issues with her nexus s, nor has my best friend with his (inc. free unconditional upgrades) I'm not saying apple is bad, just saying the experience hasn't been as rosy as I would have "expected" given all of the pro IOS hype I read about, and the big price difference I paid vs the nexus s.
