iPhone OS 4.0 sneak peak because of the launch of Microsoft Pink phones?

Seems like Apple and Microsoft are at it with each other again. After rumours of a Microsoft event on Apr 12 on the supposedly launch of the Microsoft Pink phones, Apple has announced an invitation-only event on April 8 for a special preview of the iPhone OS 4.0. Obviously, they are trying to make sure Microsoft has a hard time launching any mobile phones. Judging from the early sneak peaks of Windows Phone 7, it just looks like a phone that copies the features of the iPhone and Android. Windows Phone 7 even copied the early iPhone's capability of not having cut, copy and paste.

Regardless of the rumours, I still feel that Apple will not enable multi-tasking on the iPhone. iPad maybe but not the iPhone. The screen estate is too small for any effective multi-tasking. For efficient battery life utilisation, push notifications and saving of states are still the best ways for multi-tasking on the iPhone.

I guess we'll know more about the rumoured iPhone OS 4.0 come Fri Singapore time.
