So, was I the only one who noticed that Dooku’s lightsaber handle (and here) was somewhat V-shaped? I kept expecting him to do the dual-blade thing, but I really couldn’t think of any positive benifits of having a V-shaped lightsaber. So did he have it that way just to have a better grip on it?
Yes, I noticed that the toy only has one blade, but that’s certainly not definitive.
Correct. I get a better grip on it this way.
(This will be my last Dooku username joke, I promise). 
Seriously, when he first turned on his lightsaber, (or maybe the 2nd time when he turned it on again to fight Yoda), I noticed the fancy shaped handle, and assumed it was b/c it fit the fencing-type way in which he was holding it off to one side. So I would say yes, for comfort’s sake / to get a better grip on it based on his fencing style.
Ergonomics?
looks like a gas pump.
Certain General Mills cereals (including Cocoa Puffs) have lighsaber shaped pens as prizes in the boxes. The one of Dooku’s has a pistol-ish grip, as in the movie.
I thought it looked a bit like a next gen phaser.
A fencing foil will have a slight curve in the grip to assist in keeping the palm held upwards while fencing. If you get lazy and put the palm facing down, your opponent need only push down from the top and your foil is pointing down, making you defenseless.
A foil doesn’t seem like it would have much advantage over a saber. I would think saber fencing would have no problem overcoming foil fencing.
The curve is an exagerated Epee handle.
The curve makes holding the sword (RL or lightsaber) easier. I practice on a weekly basis with a reenactment group with something similar (minus the hollywood eye-candy looks).

other side of the coin, a saber does not have much of an advantage over a foil (or epee) Traditional saber does not use the tip as a valid form of attack. A foil does. Hard to position a saber into a position to attack when someone is going to poke you.
a "pistol grip foil or epee gives a great deal of point control when handling a weapon.
None of the lightsaber duels I have seen are classical, fencing styles (foil epee or saber) but a combination of all those styles plus a few more (kendo) as well.
just my two cents.
Doh! should have previewed that… Skott wrote the first paragraph after the failed “quote”
I thought that the curve was purely ornamental. Something elegant for the Count.
