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.
I don't member the exact model but I had an LG Voyager that i held onto for a long time... I did NOT want to give up my physical keyboard for the touchscreen keyboard so I held out as long as I could. If Samsung came out with a slide-out keyboard for smartphones I'd be on that shit right away.
