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.
Sony Ericsson W810i. Got it in 2007, I think. When it started to die on me in late 2009 i replaced it with an iPhone 3G, which was my first apple phone. It was also my last apple phone as I hated how locked down everything was.
EDIT: I just remembered I had a secondary dumbphone around 2012 or thereabouts. It was a dual SIM nokia of some sort that I used mainly as a backup phone in case my main ran out of battery while I was on the move.
I had a Sony Ericsson too as my last dumb phone but I don't remember the model. I just remember it slides out to reveal the number pad and that it was great for music.
