Not to worry. My replacement unit arrived the next day and I was soon up and running. Make that crawling. Nothing about the iPAQ is fast. Screen refreshes take time.
Navigation is sluggish.
The modem is rated at 56K, but it seems a lot slower. Microsoft says the new user has nothing to compare the laggardliness with, and will appreciate a leisurely pace to learn the device. While that may be, the unit seemed slower than it had to be. The iPAQ comes with USB capability for attaching a printer. Good move, but I would also want to add a mouse.
