So had a hands on with the iphone5. Honestly its not a game changer. I would still get one if I didnt have a phone but andriod phones would be in with a shout. Doesnt make me want to upgrade from a 4 nor do I lust for it.
A good service with plugs is a nice refresh.
Pulleys are cheap and can be done when changing the belts. You could also remove the idler pulley. Stubby and or bose hack or the tape that goes in and lets you plug an mp3 player in. A free suspension check could be worthwhile and see what needs attention?
I use the mobile version probably 60-70% of the time and this update has made it much easier. Never really noticed re the pictures but I'm always connected to wifi.
I dont get on with service manuals TBH as they dont actually show you get to what your doing. The haynes is good like that plus I used it alot and it was £15. I've made my money back from it plus its a good read when bored.
