I distinctly remember the Autumn day of 2011 when we stood in the line of the local Best Buy in West Des Moines to grab one of these. It was miles ahead of anything that was in the market that time. It could do multitasking and had a lovely intuitive UI (cards!!). I remember being blown away by it. Android and iOS freely stole features from it later.
I still have the device and it’s one of my cherished vintage devices.
