Also the initial home screen paradigm is completely same as PalmOS, sans the categories.

Heck, even the notification screen and widgets screen is an evolution of the Today.prc from PalmOS days.

I need to play with my LifeDrive more. I miss that beast.

Also, Graffiti was the best on-screen ink implementation. Change my mind. :D

Fun fact: Palm's latest phone copies iWatch's user interface to a phone interface and makes it usable on a bigger device, it's both fun and awesome in so many levels if you ask me.
