I like a kickstand, but having ridden without one for a long while I've learned to live without it too.
I reckon if you regularly need to park you bike places without bike racks you would benefit from a kickstand.
Can't say I do, but I've felt like it could be useful when I've had to pull the bike away from the stands to load up 30+kg of shopping and the bike's flopping all over the place.
Anyone using kickstands / steering stabilisers on their functional bikes, or is this all just needless tat that died off for good reason.
