Adam,
I hope you're just kidding about the 6315, it's the slowest of the PPC PE devices out there, not to mention B/T profile issues, calls going to VM, etc. TMo can't even sell these after the initial honeymoon. The ONLY thing it has going for it is the good battery life, at the expense of processor speed naturally.
For a device in this category, the best performance is probably the HTC "Blue Angel", which is branded as XDA III / MDA3 / PDA2K / SX66 / Qtek9090 (forgot what Verizon calls theirs). The slide-out KB is much better than the clip on from HP. I had the SX66 for awhile and decided size matters, so I ended up getting the imate JAM.
As for the 6315, it has been one of the most problematic PPC-based devices I have deployed.

I had a Seimens unit last, and now have an Ipaq myself. The detachable keyboard is nice and I prefered it to the Samsung for that reason. No need to use the stylus if I don't want. It's bluetooth and WIFI, it's got Windows, has a camera, all the Microsoft programs like word, excel, media player, ie, etc. I keep a gig memory card in it with lots of music, etc. Way cool. Best unit I've had. Better than the Siemens Pocket PC and the Nokia Communicator. </div></BLOCKQUOTE>
