I have owned my Samsung i780 pda for about 3 months. First let me list the things I love about it first, and then the things I would like to change:
Things I love: It gets great reception and has a nice, clear speaker phone. Most pda phones are also only touchscreen. But this phone can be either a touch screen or it has numbers you can actually dial on the front of the phone. It also has a slide out full keyboard which is awesome for texting and for surfing the net. Lastly, it syncs to my computer so it is very easy to work when I only have this and I am away from my computer.
Things I don't love: the touch screen can be difficult to navigate without the stylus. I wish the touch screen buttons were larger so that I could use it more like an iphone. The other thing I don't care for is that the camera is only 1.3 megapixels. It takes decent pictures but not great.
But overall this is a great smart phone and I would recommend it to anyone!
