I'm in the opposite boat. I have an Android phone and an iPad. Honestly, I can't imagine using iOS for a phone. The notification system is completely broken, the lack of widgets or any useful way of getting to your data (which is what I need in a phone), is just weird and counterproductive. That being said, as an entertainment device (Netflix, Civilization, other video games, music, etc), makes a lot more sense, and the resources are used much more efficiently on iOS due to the restriction on background apps (freezing the app most of the time, but not always) and games can be done better on iOS due to the pixel perfect resolutions and development. I only really do one thing at a time on my iPad, but when I do multiple things, the ability to multitask is "good enough" for entertainment.

Personally, I jailbroke my iPad because AdBlocking is a requirement for any device I own. The least intrusive visual ad service (Google Text Ads) even tracks your internet usage to extremes, and they have been hacked to be serving malware multiple times. I might find ads annoying, but the privacy invasion of tracking what you are doing through Facebook Like buttons or Google Plus buttons or ads is too great for me, and the usage of a centralized system that is on nearly every website that could be used to serve malware is just unacceptable to me.

That being said, the additional 4x4 folders was useful as well, but I haven't dug through Cydia enough to know much about what else is available.
