Zippyt,
The T|X has all of that, and then some. I have a Tungsten C with Documents to Go (I should get 8.0 of this), and I can copy files to an SD card, plug into the PalmPilot, and go.
I highly recommend getting the T|X with Documents to Go 8 because you will be able to:
1. Open Office documents natively (I do this with Word, Excel, and Powerpoint). I do not carry a notebook with me to meetings to read Word documents. I carry my PalmPilot, and edit the documents natively on it.
2. Open PDF documents natively with Documents to Go 8.
3. Run TCPMP and put your videos on the SD card along with your MP3s without converting them
. TCPMP will play many video codecs on the Palm.
4. Open whatever else you feel like that has a program to do so.
I am running a Tungsten C because I need the keyboard on it. I paid $250 for it, and another $50 for an SD card got me a solution that lets me do exactly what you are talking about.
The T|X also comes with software for synchronizing with Exchange 2003.
The T|5 had/has very serious issues with the OS which were fixed in the latest product revision, known as the T|X.
My advice: Return the T5, get a T|X and Documents to Go 8.0. You'll thank me later.
Thanks,
Mitch
