Using task killers and the like does more harm than good - Android does a very good job of managing memory by itself and it will kill apps as needed, while at the same time using any available RAM to keep apps in the background.
What task killers do is force close apps to keep as much free RAM as possible (what's the point?) - the effect is that when you come back to an app it needs to be started from scratch instead of simply being pulled form the background. This takes time and is CPU-intensive, therefore eating more battery.

the "free up as much ram as you can" thing is kind of a double-edged technique, if you think about it, the un-occupied ram is being wasted but at the very least it is ready to be used by tasks that would need them without delay. on the other hand if you didn't kill tasks and just reserved enough ram for the next program then wouldn't that be more efficient?
if you got tons of ram you wouldn't need the task killers anyway.
i wonder if those phones have a throttle program, something that forcibly throttles the CPU to slow down, this could help prolong the battery-life, also screen brightness can be lowered for saving up more battery-life.

It doesn't really take any extra time to close applications to free more RAM when it needs it. It knows which programs are safe to close and just overwrites them in memory as needed.
I think it is possible to over/underclock Android phones, but you need to have rooted it, and be using a rom that's able to do it. I imagine doing so would reduce power draw too, but only when using really intensive applications - and the trade-off would be that those apps would run slower. Since when it's idle it's not really using much power anyway, it only uses a lot when under load.
kitamesume:
well true the programs would slow down considerable, but what if you set it to throttle lightly by 70% battery-capacity? and throttle aggressively when battery hits 35% or below? it would prolong battery-life considerably.
i think management is the best way to prolong battery-life, if you use apps on the tablet really frequently then it wouldn't last you long. but if you manage your usage and only use intensive programs when you're plugged in then you could even prolong battery-life to more than it originally can.

If I don't really use my phone - short of phone calls and texts, which is pretty much only what I use it for anyway - it can last me close to 3 days, 2 comfortably, permanently connected to wifi. When bored at work, browsing the internet I've run down the battery from full in about 5-6 hours. My phone (Sony Ericsson Xperia X10 Mini Pro - I know, what a retarded name) has a far smaller screen than yours too. Turn down the brightness of the display as much as you can bear; this is what'll kill your battery life far more than anything else.
