Anyone use this phone, or any Windows based PDA with Quickbooks integration? My wife and I both have our own companies and would like to add some. I have a PPC 6601 and would love to be able to invoice a client on site and either print or email and invoice. My wife needs to be able to write up an invoice and print to a mobile printer with IR capabilites, she is using an older IPAQ with WM2000.

Any thoughts on Quick Book Wireless Invoicing 1.0?
DwyerTech MobileBiz 2.0?

Obviously the cheaper the better, but only if it gives us what we want!
