The caffeine in tea seems to be absorbed more smoothly than coffee's. An amino acid called theanine (http://en.wikipedia.org/wiki/Theanine) helps counteracts some of its negative side effects, especially the nervousness.
You can get theanine on its own as a relatively cheap nutritional supplement. (It tastes distinctly like Japanese green tea, which is often shade grown in a manner that greatly boosts the theanine content.)

I found its the sugar in coke/soft drinks that really makes it unpleasant. I am sure tea is lots better - the general health benefits and some caffeine, and not the toxic amounts of sugar (and if in the US, its high fructose corn syrup which is really much worse then just sugar).
I've read a contradictory article in the past. Wish I could find it, but it mapped out chronic usage of tobacco & caffeine on chess players. The findings were pretty clear for both coffee & cigarettes: '+' to the mind '-' to the body.
I simply cannot live without coffee... the very first cup in the morning is one of the most enjoyable parts of my day ;)
Taking the article seriously, perhaps your statement could be rephrased "I cannot live with caffeine withdrawal."
BTW, taking one or two caffeine pills (50mg) per day can see you through the withdrawal period with no headaches.

So I guess enjoyment of the taste and smell of coffee does not factor into it?
Or am I speaking like a true addict?
I have a particular appreciation for a well brewed cup of coffee, without it, the day simply isn't going to go right.

Sure it factors. That's why pills help during the withdrawal, because they don't trigger the full pleasure ritual, which includes taste, smell and anticipation.
But note that every ounce of pleasure you extract from drinking coffee is exactly balanced by the pain of withdrawing from it.
(And, in between, successive cups do not generate additive quantities of pleasure.)

It's a dilemma. I love the taste of coffee, and some things just don't taste right without it. On the other hand, drinking coffee means being addicted, and being addicted often means drinking really, really bad coffee if it's the only caffeine available.
I've been deploying an alternating days routine (a day with, then a day without) with caffeine to try and avoid dependence. Sometimes I'm not sure if I'm getting the best possible outcome (good effects of caffeine without dependence or developing tolerance) or the worst (dependent and tolerant but torturing myself every second day). This article would suggest maybe the former, but sometimes it feels like the latter :-)
My personal experience: doing without coffee for a day or two has no effect. Also somewhat oddly, there is one particular place I go where I get a `mocha latte' and it wires the hell out of me. (It is a great time for coding.) Not sure why.
"What this means is that consuming caffeine regularly does not appear to produce any net beneficial effects, based on the measures we examined."
Depends on your definition of "beneficial effects", I suppose.

I don't think so. As with any drug abuse, your body develops a tolerance to caffeine. Over time, you develop a drug dependance on caffeine; you require more caffeine to feel as awake as you did before your drug dependance developed. Thus, there is no net beneficial effect.
The pleasure experienced while consuming products that happen to contain caffeine is a beneficial effect, no matter what the study says.
It certainly is. However, don't discount the corresponding hangover period.
Since there is no time-averaged gain in pleasure, presumably the benefit lies in being able to time the pleasure, say to compensate for mood changes due to other factors.

Net zero? No. This proof you have constructed is ridiculous.
Steroids are the same in these regards. Your body builds up a tolerance. When you let your blood levels of the drug drop, your testosterone production is lower than pre-drug.
So these must cancel out right? Heavy steroid users must be the same size as weight lifters who worked as hard without the drugs?

Yeah. Caffeine wakes you up when you start taking it, allows you to function during the period when you're taking it regularly, and makes you drowsy when you withdraw from it.
I used to drink rather large quantities of coke. Since I stopped (and yes, it took a week of headaches, though after I started drinking tea it got a lot easier) I find not only I'm in better shape overall but I sleep much better at night. I guess the trick is very small amounts and good timing.
