Nokia n900 for me, circa 2010. It ran Linux (real Linux!), had a pretty good camera, headphone jack, sd card slot, slide out keyboard, 4or 5 day battery life, xmpp instant messaging natively. It was perfect. It was a little bit chunky, but would fit in a jeans pocket perfectly and didn’t weigh too much.
