iPhone : ios 5

[Will]

Whilst there's a thread on iOS 5 - thought I'd add some questions in here if that's ok?

Location services seem to be always "on" - and I'm worried it's going to drain the battery dry more quickly.

Also, what is the "localise iPhone" - I know it's a remote control/management app - but how does it work?

Things I like, using the volume + button to take pic, pinch movement for camera, picture editing. The reader function within a webpage to cut out superfluous information. Taking a pic when phone is locked.

The information screen (when you swipe down) thing don't really see the advantage of that to be honest, though the notification not taking over the whole screen when in an app is good. If you could add wifi, bluetooth etc... to the swipe down thing that would be useful. But all I have on there is the weather and today's appointments which frankly doesn't add much speed/useablility.

The "tasks" app is pointless as what's the point in having a diary and a task list?!

Mail feels a bit slower, and it doesn't seem quite as "slick" but I'm sure it's probably in my head. The functionality improvements do enhance it though.
