I'm looking to buy a PDA, but there are so many out there that I need help deciding which is right for me. Here is what I would like to have: Calendar (obviously) that synchs with PC, preferably M$ OS, just so i can have excel, etc on PDA, and I would love to have a good amount of music on it. Wi-fi would be cool to have too. Don't want a total brick to carry around, but if thats all that is available now adays i could at least look at it. Price is not an object here. Is there anything like this on the market that you know of? Links?
