often have several apps open
- shell
- browser (several pages)
- notifications
- SMS text entry
- email
- (sometimes) media player ie whilst browsing listen to radio/music
- f1 timing data
- GPS tracking running in background (recording a log to merge with DSLR pictures)
- or possibly satnav app running esp if WALKING (if driving am not touching phone!)

When running these I have a habit of quickly flicking -- for example between web pages, or perhaps between a web page and a contact. I may cut/copy text

Typical is probably 6-8 windows

There's also a variety of more hidden/background apps rnuning, including of course fmms, but also apps to manage connections, IM,etc
