I, too have a BioLite CampStove. I used it last summer when car camping in the White Mountains. On the same trip, I also used the Woodgas Camp Stove LE, which comes in two larger sizes. The stoves use similar technology, adding air to the burn chamber to aid in burning the biogas that is additional fuel otherwise lost. The air is added by fan holes between the inner burn pot and the outer solid chamber.

BioLite CampStove pros:
compact
good for car camping or bugging in/out
very sturdy fold-out tripod legs
easy to change fan speeds
charges its own fan battery
very little smoke once started
pan rest is an integrated tripod, and does not intrude on feeding the fire
can burn most any dry biofuel (pine cones, twigs, bark)
charges low-power USB chargable devices with excess power. I've charged an iPhone4, iPod touch, LED/laser flashlight, Petzl Core headlight battery.
when cool, fan/power unit nests in burn chamber
only two pieces (burn chamber & power unit)
heat is more focused with a smaller diameter burn pot (v. WoodGas)

BioLite CampStove cons:
heavy for backpacking (2 lbs)
entire metal canister and legs get hot (stove can be moved by holding the power pack)
a bit finicky to get started
$129

Woodgas Camp Stove LE pros:
compact
sturdy--though I did manage to knock it over twice when camping.
bottom (fan below burn chamber) does not get hot
dual use handle/tongs
very little smoke once started
can burn most any dry biofuel (pine cones, twigs, bark)
pan rest stores flat
$53
light weight
can store all pieces and some fuel in cool burn chamber

Woodgas Camp Stove LE cons:
changing fan speeds is a bit clunky (unplug battery pack from "LO" and plug into "HI")
needs charged batteries
pan rest is intrusive for feeding fire
pan rest has to be carefully removed and can easily come apart
several pieces (burn chamber, 2 pot rest pieces, battery pack, 2 batteries, tongs/handle)

And just today, BioLite sent an email to early adopters stating that they will be selling a grill attachment. I will update my review when that is available.
