I personally like cartomizers (cartos) and started with 808s because I was like you -- I wanted something that looked like a cigarette and I also wanted convenience. I didn't like the idea of the 3 piece 510 and wasn't looking to drip or anything else. Even now, dripping while trying to drive or out and about is a pain and, personally, I haven't found dripping to be better than cartos.
Like dlbald said, you might get disappointed in the battery life of an e-cig that looks like a cigarette. I was that way and moved onto the 901 Riva pretty fast (works with 808s perfectly, it's sold by CigEasy as the Elegant and Vapornine as the Defender). The 901 Riva is still pretty small -- I can palm it. Now, I'm using a Buzz. I basically tossed the idea of looking like a cigarette. I have friends, though, that won't touch anything that looks like a cigarette regardless of the battery life issue (they'll do the XL batteries and drip tips, but that's it). So, it really is a personal preference.
If you want a really good quality automatic battery that looks like a cigarette, I would say the GreenCig (not to be confused with Green Smokes). It's expensive, but the four I originally bought are still going strong and I have friends who have standard 808 batteries die on them constantly (won't charge, won't hold a charge, just break, etc.) Both NHaler and LeCig sell the GreenCigs, they look like a cigarette, work with standard 808s, and the LED is green, so people don't freak out as bad when they see it and think it's an analogue. They have a kit with a nice PCC, too (which is definitely necessary, as dlbald said, if you go with that type of e-cig).
On the e-juice, that's an option. You can buy pre-filled cartos, but you can also buy empty ones and fill and re-fill yourself. That's usually better and more economical, IMO, and gives you a lot more variety in terms of flavors, brands, etc. I just buy blank cartos and fill them myself with my favorite e-juice, topping them off periodically, and the cartos last a long time. When they start tasting funny, I'll wash them out and can usually get another run out of them.
Good luck.
