Pretty useless in laptops as it eats your battery up due to a brighter backlight...
And I wonder how I get my 3 hours of battery on my T43 because of them

I don't know if you do get 3 hours of battery, however...
there have been many studies done, and people using notebooks are plugged into a/c power something like 88 percent of the time.

As for Flexview, and IPS panels in general...
When IPS was created, it was never intended for notebooks at all, since it does use more power. However, the circuitry to support these panels has gone through different generations and iterations, and each one gets more and more energy efficient.

If a model is rated at 3 hours of battery life, that is with the wireless off, limited hard drive access, screen brightness at minimum, etc., etc. so you
are not going to get the 3 hours "real world" anyhow.

Actually I wanted to test my T43, and apparently I did get 3ish (3 hours/2 minutes at 10%)
Lets see what I had turned on/off
Wireless = Yep
Dynamic switching = Yep, no maximized battery life
Screen = 5/7 bars, it was dark anyways
What I had running = Internet browser, played pinball real fast, a small quick (VERY quick) game of command and conquers, more internet...

And you're right, I have my laptop in AC power only to preserve the battery right now. And isn't the T43 rated for 5 hours of battery?

I can get ~3hrs of battery life with still 30% to spare, with battery life maximised, wireless on, bluetooth off. So that converts to 4+ hrs if I really need to. Mostly surfing net then.

I definitely get better than three hours of battery life on my T42p, 15" with IPS. I can fly from D.C. to Seattle and use my Thinkpad most of the time on one nine-cell battery.

I do, however, turn the screen brightness down.

I wish you could get IPS on a 14.1 inch screen.
