I just got a Nokia N75, still trying to figure out how everything works. It has a bunch of cool features, most of which I will probably never use, but I have set it up so that the Jeff Beal Main Monk Theme (or part of it) is my ringtone, the inside display wallpaper is the autographed photo of Tony that you can see in my sig, and the outside display is my little Edvard Munch/Adrian Monk 'Scream' icon.

I felt it was appropriate because there always seems to be fingerprints on the display.
My last phone was a Nokia 6210, and it was okay, but I wasn't crazy about it.
My husband is still waiting for his Samsung Synch (I think) to arrive, but he will probably use a lot more of the features than I will. He had a 6210 before, too. My daughter has just gotten her new LG CE110, and she likes it so far. Her last one was also an LG, but she jumped in a pool with it in her pocket a couple of months after she got it and it died.
Spinner, I rarely actually use my cell phone, and I am always leaving home without it, I forget. We don't have a landline anymore, though because just using the cellphones seemed more practical. I was resistant to getting a cell phone for a long time, till we topped a hill where a big truck had lost a brake shoe, which punched a hole in our oil pan and left us stranded in the middle of nowhere. My husband could hardly wait to say, "You see?! *This* is why we need a cell phone!" I forgave him, it's so rare that he gets to be right that it went to his head.
Teresa, I think that most, maybe all of the cell phones for the main characters on Monk are Motorola, it seems that I have seen that 'M' that is their tradmark on most, if not all of the phones since the first season, but in most cases, I couldn't tell you what the model of the phones are, they seem to mostly be the lower profile models and until Buried Treasure, it seemed to me that Stottelmeyer, Randy and Natalie all had pretty much the same model, or close enough you couldn't tell the difference at a glance. In Buried Treasure, though, Randy had what looked to me like a red Motorola RazR.
