My Palm Tungsten E PDA has died a watery death, and apparently they aren't sold anymore, not new anyway. So what should I get to replace it? I really want a multi-tasker, keeping in mind I won't be using it as a phone (I have one I like and I don't want to sign up for another plan).

Something that is compatible with Windows is best; I need the ability to open and use MS Office documents, export from Outlook, read PDFs, e-book capability, and of course play music.

If you suggest a smart phone (and I really don't want another phone) at least say which one matches my needs and doesn't require that I sign up for a phone plan. Thanks!!
