Ok, I'll play...
What I would like to realistically see in iOS 5?
1) Widgets
2) Notification banner. Just a little scrolling banner at the bottom of the screen on the iPad (I am not a smart phone user, so I don't care about the iPhone). While I am happy with the numbers that are displayed on the application icon, I get migraines reading the bitching going on about the notications. Just a simple banner like they have at the bottom of the Daily App (app blows btw) scrolling your notifications.
3) Wireless backups and calendar / contact sync. I get all my data wirelessly now anyway, but it would be nice not to have to plug in to update calendar and contacts. Come on $99 a year for Mobile Me?
4) And while this isn't an iOS issue, it's just that I haven't bitched about it in a while. Maybe I'll give the right person a migraine and they will do something about it. What I need is big boy Excel. Numbers unmerges merged cells. Come on Apple really ? Microsoft, how about REAL Excel for the iPad ? Please.
That's my thoughts.
