This is the best iOS update ever. As a developer, I can't see how Apple can release a better iOS.

I was quite disappointed by Lion but after watching the video and looking through all of the features. I'm impressed.

In the end, it is not about spec list. It is about experience, speed, UI.

Notifications on iOS is so much better than Android. Yes we have WhatsApp but iMessage might be faster as it doesn't have to launch. So, iMessage for all iOS devices and WhatsApp for other platform.

Multi-touch gestures for iPhone doesn't make sense even. 3-finger swipe to change to other app? Ridiculous.

iCloud integration, that is deep inside iOS5. If you're a developer and you see the kind of things that is in iOS5, you will be stunned.

Android/Google pretty much lose everything. Everyone will move to iCloud and dump their Gmail. I know I will.

SMS and iMessage is mixed together in the same app on iOS5. How you differentiate between both is looking at the title and colour of the Send button. That is for iPhone only. On others, you can only send through WiFi and I'm guessing that it will hold your message and sent it in background when you have WiFi.

I'm not sure but that would be how Apple does it. I have access to it but still using iPhone 3G, so can't test it.

iPhone 5 will never be released in November. The latest would be October, usually Macs. November would be too late for the Christmas. iPhones will probably reach here late.
