I don't see the problem with Symbian
I have a Symbian touch screen smart phone (Nokia X6) and I honestly can't see why so many people seem to think it is no good. It seems to me to involve far less hassle for normal day to day functions than my Girlfriends Android phone (note, I am a Linux desktop user by choice, so i'm hardly biased against Linux based stuff in general). eg: Perhaps you could explain what is supposed to be wrong with the email client, it works perfectly for me.
Because of this decision by Nokia, my next phone will probably be an Android, and therefore not a Nokia. Nokia lost my loyal custom with this decision (my last 5 phones were all Nokia/Symbian) and I suspect quite a few others will make the same decision.
Also, please remember the human cost. The developers who remain at Nokia may like the new tools, but a lot of people have been made redundant in Finland because of this decision, so I suspect the opinion of those developers that remain is coloured by a strong desire to tow the line and keep their jobs.
