Having used ios 7 on my ipad and iphone 4, I have hated nearly every aspect of it for the past month. My iphone 4 has became unusable because it is not upto the job of running ios7 (it was perfect on 6!). Maybe I'm paranoid and think apple done this so to make us update to the the latest device? Either way it made me intqrigued to try android os. And to be fair. For what I want out of my devices it seems ok. Especially moving my music over to google music in the cloud, which is one of the main functions of my phone.
