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.
My "iPod Classic", for all its faults, had survived going under a bus's wheel unscathed and falling off my bike at speed a few times before I finally consigned it to the box of electronic stuff I wasn't going to take with me when I emigrated three years ago. The Gameboy colour's in the cupboard as I type! I might even bring it with me when society collapses and I have to forage.
