This pretty much sums up my experience when I switched from my iPhone 5 to a Nexus 4. There are pros and cons, but it takes a while to get used to the change, for better or worse.
One striking thing, as I have noted in some updates throughout the body of this article, is how many of my observations can be addressed through third-party apps that would be impossible on iOS. Background services that sync iCloud calendars to the Android calendar list, for example, or third party apps that install AirPlay services. This is, it seems to me, a key strength of the Android offering — that third party apps have more control over the operating system, more flexibility to serve your needs. Of course with great power comes great responsibility; this very control leaves the door open to all manner of malware. I’ve certainly been wary of installing random apps from the store, rightly or wrongly, finding myself scrutinising the trustworthiness of an app in a way I never would on iOS.
