If you're going to spend $200, buy the iPhone. I love mine. I use "Docs to Go" to access my Word, Excel, and PowerPoint documents. This app allows you full editing capabilities. It syncs with Outlook for mail, contacts, and calendar, but although it will give you an alarm when tasks are due, it has no direct interface with Outlook tasks - the only low point as far as I'm concerned. BTW, I have a photogapher friend that uses her iPad as her portfolio. Beats carrying around a big album.
