Single speed v geared: FRICTION
Suppose you have a geared bike and you're currently in the 42-17 gear.
Now suppose you have a SS bike with 42-17 gears.
Will you be able to spin faster on the SS because there is less friction in the drivetrain ?

The amount of friction added by two derailleur pulleys is going to be deminimis.

assuming the chain is tentioned properly.... not a significant difference.
if the chain is too tight (how most customers chains are when they bring them into the shop) it will be harder on the SS.
does the geared bike have ceramic bearings in the jockey wheels?

The Arrospok will negate all advantage.

Nah wasn't trick question, I just thought there would be more resistance. I guess there is but like some of you pointed out, not a whole bunch. I was just trying to understand the benefit of single speed bike versus a geared bike on which you never change the gear.
If I bought a single speed bike or just rode every where in the same gear (on a geared bike), would I be missing out on anything. So I guess there's no need for me to waste brain cells thinking whether I should get a SS bike or not... I'll just stick with geared bikes.
(Ps: yeah I know about the other benefits of SS - slightly lower weight, less maintenance, but it's only slightly less weight and only slightly more maintenance, not a big deal).
PPs: I'm not bashing SS, I'm just convincing myself why I shouldn't buy one.

The advantage of a SS/FG bike is the simplicity. When I get up in the morning, I need to ride to work to just work. I can't have it in the shop or down for maintenance, and there is just less that can break on a single speed. Cables don't stretch, less parts to lube, etc. Also, when I leave it locked up outside in the rain, I don't have to worry about it.
Also, for all you weight weenies, instead of saving a few grams on drivetrain components they aren't there, so it's the ultimate weight savings
