6610 is a good phone, great looks, very good sound quality.
It has a good battery life, I am using it since a year, never needed to change the battery. Talktime is about 2 hours.
But its price keeps on falling....
A year ago I bought it for 11500/-
I heard Nokia is going to replace it with a camera phone..
currently its available for less than 7000/-
I like the display its better and keypad. But its polyphonic tones arent any better than a Samsung phone. Hardly audible and only 4 tones.
FM radio reception is good.
Software : could be improved. When a get a call and want to add it to a name, you need to navigate all the from AtoZ to reach whatever name you want to reach alphabetically, the search could be provided there!
When you get a call from an unknown number and you have set alerts only for certain groups you do not get alerted, I think there should be facility to get alerts from certain groups excluding the ones you want plus new unknown numbers.
