Well, at long last I can say that my upgrade has shipped. Sadly since I specified second day delivery, it apparently isn't due till Monday. However, just knowing it's on the way after so long is quite comforting; and frankly, a bit surrealistic :).
I ordered it on the 25th of June (the beginning of Summer) and now it is going to arrive on the 22nd of September (the beginning of Fall). If anyone would have told me that I would litterally be waiting all summer long for this thing when I was ordering it, I wouldn't have believed them.
However, after all of the frustration and delays surrounding this thing. I must say that I am still grateful that Dell chose to make it available to us, and that they followed through in the end. It's more than some other manufacturers did with PPCs more expensive than the Axim.
Now, my problem is with deciding whether to actually install this thing right away, or wait for WM2003 and the software out there to mature a bit before switching.
