iPhone 5s vs. iPad Air - Upgrading from iPhone 4/iPad 3rd Gen.
I hope I'm in the right forum here...
I currently own an iPhone 4 (16GB, black) and an iPad 3 (64GB WiFI + Cellular, black). I want to upgrade one of these devices but I'm not sure which. My use-cases are the following:
I use the iPad at school for writing and organize homework. I notice some lags while switching between apps, e.g. from Pages to an dictionary or my timetable/homework-app. At home the iPad is used for doing homework and some Twitter/Facebook and web-surfing and watching TV-series.
I use my iPhone in the bus for listening to music, chatting and some Twitter/Facebook and web-surfing. Switching between apps takes quite long and after switching apps need another bot of time to be responsive.
Data plans and contracts are not important since I'm a prepaid-customer.
I'm absolutely not sure about whether device I should upgrade and I' love to hear your opinion. Thank you!
