Yes, Treo is what you are looking for. Different PDAs have different abilities. iPhones are music and multi media devices but aren't useful for documents and corporate email. Blackberries are practically dedicated email devices with a phone attached that aren't much good at documents. Treos are multi-use devices that handle emails almost as well as a Blackberry and can view and edit almost any kind of a document. Excell, Word, Adobe, a Treo can do it all. I looked for more than a year to upgrade my phone to the best option - I have a law firm - and Treo was what I settled on.
