Nothing feels better than the original iPhone.

Solid, tactile, and just the right size. Mine finally got stuck in a boot loop earlier this year, but I keep it in my desk drawer, and pick it up occasionally. The mute switch (an actual switch, not a button) is still the best.

My original iPhone (bought in June 2007 for competetive research) has started swelling and won't boot up. Still keeping it. Maybe I should store it in a bucket of sand though.
