Bought this PDA after researching for two months because of the price, design and wifi capability. It might not be the best PDA in the market but the all the features I am looking for in this machine. The screen was large and display was clear. It is easy to navigate and the keys are intuitive. The battery life is excellent and charges quickly either through USB and wall adapter. I bought a SD card as the external memory but it also able to read MMC card. The media applications were sweet- the sound with earphones is good and the video playback was smooth and clear. Other business applications were up to my expectation and needs. The WiFi is great. I was able to browse the internet efficiently and it was able to detect fairly strong signal at times.
