I've been looking for a handheld device without phone capabilities for a while now, and haven't found anything appropriate. I used the ipaq110, but found it extremely fragile, and was not impressed with the battery like.

Looking at the n810, my main use for it would be school. I have one year left of highschool, and after that I want to go into compeng. So here are my questions. Does the n810 come with any address book or calendar apps on it? If not, are you able to install other apps on the device, and if so, are they readily available. I assume you would be able to since it's a unix based OS, but I thought I better ask before investing the money.

Thanks for advice in advance.
