Not sure if this needed a new thread, but this morning I was shopping the possibility of switching to AT&T from Verizon and the Z10.... And guess who walks through the door...Samsung rep!!! He allowed me to play with the S4 for a minute, I now must say that I am impressed. After the unpacked event I was sure I was going with a z10 for a different feel, but mind has been made up...I am going S4. The device is as smooth, if not more smooth than the s3. The screen is gorgeous. And the software was nothing short spectacular, especially the camera functions he demoed. The selling point was not that. The freaking build quality was HIGH!! Not that the s3 was not a nice phone, but this phone feels more solid while being lighter, smaller, and having a large screen. The metal band looked real, has me fooled. It was HTC build quality good. I thought the device looked blah at unpacked, but the front and back look awesome in person. This device is expertly crafted. Plastic is not a bad word in the hands of the right person. Very nice device. If you are thinking of getting another device and don't mind Samsungs touchwiZ, I say hold off, you will be impressed.
