Sturmey Archer 8 speed hub. It can't be beat for stop and go and go fast urban riding.

If you're riding primarily in the Flats, then get a single speed. However, if you're ever confronted with a huge mountainous incline, then your extra gearing will be sorely missed.

Besides the MTB's the only bike that doesn't make the errand rotation is the 3 speed... so another for both.

If you're just switching between 2 gears, you can easily adopt a single speed.

Both. I run my single-speed with a freewheel. I never got used to fixed.

I rode the Big Dummy today, so I had a bunch of gears I didn't need. :)

The poll options need to include "both".

I have geared bikes, single speed, and fg bikes and a number of IGH equipped bicycles which fall under the geared category.

If my ride route is going to include a lot of hills / wind / loads I ride a geared bike and if it just me staying high and out of the valley I often use the ss or fg bikes.
