I have been a palm/treo user for over 4 years, and can count on the fingers of one hand the times I've opened the calendar app. I need a device to 1) browse the web in a legible usable manner 2) connect to email 3) do instant messaging and 4) Skype. It needs to be portable and have a good chance of connecting to wifi while i travel. Right now the N800 looks pretty good for what I need.
