Favorite "dumb" phone you ever owned...
Mine was the LG VX8700. I absolutely loved this phone. Thing was a tank and I never had one issue with it in the 2+ years I owned it. It just happens to be last phone I owned before upgrading to a smartphone (OG Droid). I remember receiving compliments on the phone even well after the release of the original iPhone - which I think is a testament to the phone's design. Even with its 2 megapixel camera, I would argue this took about 100x better photos than the original Droid ever did - which initially immediately made me regret upgrading.
One of my favorite details was how when the front display wasn't active it took on that mirrored effect - which just added to the overall chicness and panache of the phone.
Loved the clean back-lit number pad for texting at night. I know most phones already had this but with its overall look, it immediately reminded me of the powerbooks/macbook pros.
