If I may jump in on the tag end of this one: I've tried several approaches, all of which are ostensibly for "poor-boy" field data collection including the use of a Pocket PC (HP or Dell) with the compact flash GPS card and various kinds of software. All left me a bit disappointed.
What I've fallen back to is my old and revered Magellan Meridian and download cable. I use the Magellan to record the field data with appropriate notes etc. Then download it to GPS Utility (http://www.gpsu.co.uk) which lets me save the file as any number of possibilities includin MI TAB files or ESRI Shape files AND runs a host of conversions from the raw WGS84 data to any flavor of NAD or whatever you happen to like -- and it seems reasonably accurate. Then I just take the data that GPSU has filtered and plug that into my MI models. Works like a charm and is much easier than fussing with all the bits and pieces of a knock-together PocketPC rig in the field. I may try some more single-unit hardware in the future, but for the moment this fills my needs doing archaeological investigations very well. Additionally, I get the advantage of WAAS support (where available) to nail down points to a meter or two.
