What are better 5megapixel (N82, Samsung Soul,k850)in terms of daily use

Go for the K850i. Sony Ericsson phones are very durable, fairly priced and easy to use. I like the resolution of their phones and the features are great. Nokias are overrated. They're more expensive and yet their values go down quickly because they come up with new models quickly. I also notice the new ones also break down easily unlike the earliest models. I haven't bought any Samsung phone but those that I've tried, look very complicated. My husband and I are now loyal SE users. When I recommended to my brother to buy an SE phone a couple of years ago, he also liked it so much that he and his wife also switched from using Nokia to Sony Ericssons. Hope this helps!
