Andrew Carton is a great guy and has turned his love for the Treo into a great business (see Rodrigo put him on the spot here).
While browsing Andrew’s site, I saw this article on how Peter Arts, someone Andrew corresponds with, was able to leave his laptop behind by building a multi-part tool around the Treo 600. It seems Peter has been refining this tool for many years (as have I, see this quaint old article of mine from early 2000).

What this kind of discussion of mobile computing always brings to mind is the push and pull between converged devices that have everything or multi-part solutions. Each have their plusses and minuses and I think there’s room for both.
