I have to agree with John C. Dvorak's article about Cell phones, especially when he says "Grocery stores are now filled with drips talking on cell phones—as loud as they can—about their sisters.".
Now I personally have owned a cell phone from when they came out in Israel. I was working at Telemesser and we worked on related technology so I needed one. To me they replaced beepers (I had one, actually at one stage I had both a beeper and a cell phone). They were an easy method to contact me wherever I am, and had the added bonus of me being able to contact other people whenever I needed to.
But I think the situation has gotten out of hand, mobile phones ringing (at full volume mind you) in the office, people talking on a phone while driving, buses and trains full of people shouting into their phone and so on.
I currently own a 7250, and Karina has a 6610, and to be honest they are perfect for us, in fact my camera on my 7250 is probably not needed, but I bought it before the 6610 came out. I think the 6610 is the perfect phone, because it's simple, small, and robust. But then I'm not a great fan of convergence, I did own a 'cool' Orange SPV for about a week, but I exchanged it for my 7250. I have a friend with a P800 that he loves, which is fine, but I think it's just a big brute of a phone that is a really bad PDA at the same time. In fact the only feature I would like on my 7250 would be bluetooth if I ever buy a PDA, but then chances are that the PDA will have Wifi so I won't need that.
I do wish there were more rules about cell phone usage. Laws that make it illegal to have them turned on in Cinemas for example. In the UK Orange have a very cool commercial series at the start of movies to remind you to turn off your cell (if anyone has any links to the vids, I would be grateful) but it's no way near enough. I want 'no cell' areas in restaurants; a law against people screaming into phones in the street; and a proper ban on phones in cars.
On that subject, I don't get how people can hold a phone to their ear while driving, and then claim it doesn't effect their driving. I tried it a few times, and I got so scared that I won't ever do it again. The closest I have come to doing that in the last few years is to use the Loudspeaker on my phone while it's on my lap, and even that I don't like doing, and try not to.
