I'd like to expand just a little on my comment about green tea.
Green tea should indeed be exposed to lower temperatures than the black teas Mr. Orwell was accustomed to drinking. If you develop the kind of addictive love for your green tea ritual that I have, there are electric kettles that allow you accurate and dependable control over your water temperature. I use this one:
It holds enough water to fill my Bodum coffee press, and a second teapot for a fellow tea-drinking co-worker. We'll often set the kettle for 160F, fill his teapot, than switch to 170F for my genmaicha blend, which responds well to the slightly higher temperature.
Like Mr. Orwell, I'm a big believer in using loose tea leaves. The coffee press I use for tea does an excellent job of filtering out the leaves, and halting the steeping process - you just push the plunger all the way down, which quite effectively isolates the leaves from the rest of the water in the press. And the vertical shape of the press does a great job of keeping the tea hot for a good, long time. Here's the one I use -
Only high-quality, inert non-absorbant glass and metal come in contact with the tea, and the leaves are free to swim around in the entire press until you hit the plunger - not trapped in a small strainer. I've been using the same pair at work and home for over a dozen years, so they're reliable, and a great investment.
Jim Campbell pointed out a recent New York Times article concerning the amount of lead being found in some Chinese teas. It's sad and more than a little frightening that this is a genuine and serious problem, especially if you're drinking two liters daily over periods of many years, as I have. I drink Japanese green teas, and have settled on a couple sources for my favorite teas - sources I trust to be even more manic than I am about the quality and safety of their tea.
At the risk of sounding like a plant, the best genmaicha I've ever found comes from Mighty Leaf, which they sell under the name Kyoto Rice. I mention it as a "thank you" - I've been drinking their tea for over 16 years. And while genmaicha isn't for everyone, for those who love it, there's nothing better.
One last point... green tea's flavors are (in general) more subtle and nuanced than black teas. I believe they are best enjoyed without adding sugar/honey or milk. I'm not going to be a tea Nazi about it, but if you're new to green tea, why not give it a try straight; I think you'll enjoy it. And please be careful about the quality of water you use; this is one case where bottled or at least filtered water makes all the difference, especially if your tap water leaves something to be desired. Enjoy!
