What was the last dumb phone you had before your first smartphone?
I rocked a Samsung Alias 2 for 4 years before I got an iPhone 5. The e-ink keyboard was awesome how it changed when you flipped the screen open to portrait or landscape.
This small form factor running Android would be very cool! Despite a small screen, it'd probably work well enough since you wouldn't have a software keyboard taking up 50% of the screen real estate. The e-ink keyboard is a good compromise of having dynamic changing keys but still have the tactile feedback.
