This can be operated without the lid if you're afraid of plastic.
I have a kettle not unlike the one linked above. As noted, one can boil the water with the lid off and it boils water quickly. I believe my small kettle is a Narita. It's small and efficient. Staying in hotels I dislike using the small coffee pots in the rooms to brew water; not matter what the water always has some essence of coffee from the maker. So I use the Narita if I am traveling and wanting an electric kettle.
There are all sorts of small, lightweight electric hotplates (http://www.naritausa.com/product/burners.html
) that can be bought. My parents have one for traveling. You could easily pair a lightweight, flat hotplate with a small kettle of your choice. A quick search turned up multiple, relatively compact, light hot plates. Here are some more (http://www.walmart.com/ip/21582291?wmls ... 10&veh=sem
When away from the tea room, especially when traveling to spaces that have nice parks or natural settings nearby I prefer to brew outside. I previously worked at R.E.I. and have a number of nice backpack stoves but the one I stick to now is my lightweight Soto canister stove: the stove has a piezo ignition, no lighter necessary (http://www.rei.com/product/862477/soto-windmaster-stove
). Even when we fly I bring the ultra small stove head and an ultralight titanium kettle (http://www.rei.com/search?query=titaniu ... version=V5
) with its titanium lid. I then pick up the fuel canister wherever I land and travel that way (fuel canisters have been easy to find (they are recyclable after use); I take my stove with me to Taiwan each year and buy a fuel canister once in Taiwan and brew tea in the parks this way). The stove is lightweight, burns well, simmers, is quiet and I can tuck the stove and a fuel canister all neatly inside of the titanium pot. It takes up very little room and my wife and I often brew tea this way; we hike to a beautiful location set out the tea gear, attach the stove, grab some water from a mt. stream, and sit to tea.
This is a link to another stove similar to mine: http://www.rei.com/product/769473/optim ... ing-system

Here's a picture of the Soto stove in use on a recent trip to Yosemite National Park with an Evernew titanium kettle (http://www.backcountrygear.com/evernew- ... Qgod3DEAgA
) that heats and pours very well.
