To be honest I've liked Android far more than iOS (even when it has its quirks). I've found my Galaxy Nexus to far more stable than my Eris ever was. No crashes, no major OS related bugs (app bugs happen, not Android's fault though), and everything is SO FAST (the "cool" factor of a phone lasts a lot longer and its a whole lot better when you keep the same phone for two full years).
Although, thank god my mom and sister switched to iPhone 4GS's after being on Droid Eris's for 2 years. Seriously, it got annoying dealing with them saying "stupid thing isn't working, fix it please". Or asking me to root them, since they saw how much faster mine was with a custom ROM, then asking to remove root because it started acting up.
So nice letting the iPhone just take care of itself. And if their iPhones have issues, I'm completely absolved because "i dunno I haven't used iOS since 3".
