As far as I know (&brands I have previously owned) nokia stands behind their devices more than any manufacturer: http://www.symbian-freak.com/news/00...ip_devices.htm

As you can see this is not motorola or apple that just abandon devices after 1 year because the next better model came out. But even for motorola things look brighter as developers now have the ability to bring OS updates even if a device is no longer sported.

And why bother wit iphone? 3 devices and still no video call? most probably the 4th one will be a disappointment as well.

As for security that platform is a mess, how can you risk doing something when even the available antiviruses can't be used? No multitasking = no browser & antivirus at the same time...
