Well, Nokia insists on using Symbian in every single phone they make except the N900, from the very high end to the lowest end. So it's fair game to compare it to anything out there, as long as the devices are in the same class (e.g. N8 vs iPhone4). You know the saying "Jack of all trades, master of none"?

I am sure it was said before, but Nokia should have kept Symbian for the low end phones and the non-touch screen phones like the E73. For high end and touch screen phones they should have gone exclusively with Maemo/Meego.
