Now that i think about it, all I really used the PIM apps for on my T3 was to remind me when my cats needed their shots, or a before people's birthdays. Cell phones these days can store addresses, phone numbers, emails, etc, though my T3 address book did have all the contacts from my cell phone. Memo Pad was only used for HandPaw BASIC programs and I never touched the ToDo list.
Now my T3 sits lonely and dejected. The only real use it has left is a bluetooth-enabled control for telescopes My C3100 fills the roll of 'micro-laptop' much better than it could ever hope to.
