Ahh, I'm contemplating whether to change my S2 to a Lumia 900 when it comes out or not

I would like to ask some questions if you don't mind me asking

1)Does this phone have whatsapp, viber and skype? Must you pay and how much is it?
2)What are the disadvantages or the things you hate about this phone comparing with Android or iOS?
Your help is much appreciated

1. WhatsApp have. Viber coming soon. Skype have, but currently no background-services. Means cannot receive calls/text when the app is not running. Since Microsoft bought Skype, it's only a matter of time before this functionality arrives, and it will definitely be more awesome than the ones in Android/iOS.
2. Niche apps are still quite limited, for example like a Maybank or GSC app. Though popular apps are mostly there, like FB, WhatsApp etc.
Notification system really needs improvements.
Multitasking can be managed better.
Other than that, WP7 is just awesome. You will just be wowed by the design, both Nokia's hardware design and the buttery-smooth Metro UI is just... artistic. You don't look like a kid playing with silly icons. (Ha! Android and iOS users)
