I just bought my first PDA phone. The Samsung SCH-I730. Phone and minicomputer. All in one. It's great! It has built in Wi-Fi, in addition to CDMA EV-DO high-speed data wireless internet w/ Verizon Wireless, Windows Mobile 2003 2nd Edition, infrared, dual 3D stereo speakers, an SD I/O card slot, and speaker-independent voice dialing, and Bluetooth. It also has a 520 MHz processor and 128 MB of memory. This phone keeps me organized and connected. So far, I haven't had any problems with it. I have been purchasing software to make it more like my desktop PC.
