Sorry for the rude reply by our member dahawthorne, brucemc777. Your criticism of Pocket Office is not unique. WM6 promises a big improvement to the Office apps on the PPC, a testament from MS that admits it was lacking some functionality in previous versions.
Regarding your inquiry as to useful apps for the PDA, check out the video player
TCPMP, third party browsers, add-on cards that allow FM, TV, CDMA/GPRS, and all the VGA games offered for the unit. You will find more uses than you can think of with the device.
