I am planning on an upgrade so I have a few questions to you guys using k900:

1. How is the call quality after all the updates and patches?

2. With moderate use of the phone in calls, whatsapp, and browsing, how long will the battery last?

3. How is the web browsing speed? I dont mind lag, but I hate pages loading slowly although this could be due to celcom on my lumia 800.

4. Any incompatibility issues since it is using Atom instead of those ARM processors?

THanks.
