Converting (and editing) PDF documents

A short while ago I blogged about converting PDF files to Word documents. I settled on Koolwire (a free internet service) as the best option. I have just become aware of another free internet-based tool, called (wait for it!) PDFtoWord. They promise to keep the formating of the PDF file intact, a rarity among converters. The site also offers a PDF to Excel converter, and the ability to edit PDF documents online. This appears to be a major advance, as most pdf editing software is pretty expensive.
