Been using Android for almost a year now. Wasn't as painful as i thought.

Multi-tasking is absolutely an issue. I find some apps re-fresh when bought back into focus and this isnt ideal, fine the developer should address this issue, but for me it's an Android app.

But in conclusion the difference is the behaviour encouraged by Android. Although my SG Note 2 supports 'multi-tasking', I find myself pressing the home key 80% of the time and then finding the icon for the previous app i was using to return to where i was. The 1 second or so delay in holding the home key to switch apps isnt efficient and as a result i find i have 10+ apps 'open' at all times when i do use the android app switcher to 'close all' apps. Which, tragically, is all i use the app switcher for.

I feel i've regressed 3 years.
