I still prefer platform pedals for my hybrids and occasionally switch a road bike to platforms if I plan to do a lot of urban group rides. I don't like foot retention in stop and go traffic, especially in casual group rides with some rookies.
I've had a pair of iSSi Thumps for a year on one bike and like 'em. A little large but great ergonomically with pretty much any shoe. After a year and a couple thousand miles the right pedal feels like something needs to be tightened a bit, spindle or bearings, not sure. It uses sealed cartridge bearings. So far, so good, worth the $40. I'd already worn out a set of lightweight aluminum Wellgo platforms and Stolen Brand Thermolites (which are great for only $15 and should last a year or so, a few thousand miles).
