We got lucky with a ground floor apartment - hooray for concrete patios. I have a Weber Smokey Joe Platinum - one of the little portable guys, but with an 18 1/2 grilling diameter instead of 14 1/2. I named him Bobby (Hill, not Flay - I don't care for Bobby Flay) I've had it for 2 years and I love it. I prefer the taste of charcoal over propane, but I absolutely can't STAND lighter fluid, so I use a charcoal chimney starter (I named HER Charlene). I also have charcoal separators for indirect heat (when I smoke meats), and really enjoy plank grilling. I don't think I could ever own a gas grill, but I'll cook on them if I'm at a friends house cooking for a large, hungry crowd. But at that point, I usually have at least 2 grills going.
I would really like to have a little charcoal grill like that... and I would also opt for a chimney starter, as I also can't stand the smell of lighter fluid.
Right now my grill storage area is pretty well taken up by my gas grill, so no Smokey Joe. And, at this point in my life, the gas grill wins out over charcoal simply due to convenience. But if I had both types available, I could use charcoal for certain cuts of meat or if time allowed for it... because even with my hickory wood chip smoking trick, the flavor of gas just doesn't compare to charcoal.
