I love the idea of a smart-flip-phone. I even like that it doesn't have a tiny little qwerty keypad to fumble with. The size of this phone is perfect. Call & sound quality are above average. The speaker phone is loud and sounds good. The 3125 feels solid and fits the hand just right. Maybe it's just me but I have a hard time finding the right buttons on the keypad without looking. It would be nice to be able to feel where you are. The screen looks great although customizing the desktop is limited. Unlike other versions of windows mobile, you can't create or download themes.This phone is very useful as a productivity tool. You can sync it with outlook via cable and it also offers, for free, Xpress mail service which will allow you to check your e-mail and calender when you are away from your pc. In addition to business, I have gotten in the habit of entering all of those details that my wife tells me and setting reminders on the phone. This information also syncs back to your pc so that no matter where I am, I'll get a reminder about those little details and therefore I don't get yelled at anymore.This phone works as an mp3 and video player. Many video formats don't work. I'm not sure if it's because of codecs but It doesn't allow you to install codecs. The sound quality is great with the included earpieces but it doesn't have a standard earphone jack so you can't use any other earphones. The video quality is poor and becomes distorted when you change to fullscreen. I wouldn't expect anything more out of a flip phone. The built in video camera is useless because the videos come out blurry unless you have a very still subject and it's well lighted. It takes decent stills for a phone.Programs are occasionally slow, particularly if you are running more than one program. I am disappointed with the internet speed. Since this phone was recently released, I don't understand why they didn't make it 3g capable.One big complaint that I have is with the micro sd card. It is often unrecognized. I have to turn the phone off, open the back cover, re-seat the SD and sim cards and then power it back on. I suspect that the connection to the card is lost just from the constant movement that happens when you carry the phone. This happens every 2-3 days. My phone is only 3 months old and I wonder if the problem is only going to worsen with age.I recommend this phone for someone who wants to sync with outlook, while being able to listen to tunes and play games on the go and who wants a unique phone to show off. If you want a great phone but don't need windows mobile, consider the LG CU500.
