True, especially when the laptop is pushed a bit and using more power.

I've seen lots of advice that says to leave the battery charging for an hour or two after it reaches 100%. I think the thinking behind this is because the device, which shows the percentage figure, may not have yet learnt what a full charge is for your battery, so it might be saying that it's 100% when in fact it's only 98%. Remember the whole point of calibration is to teach the device the true upper and lower limits of your particular battery.
I am pretty sure it won't make a difference. Once the fuel gauge detects the battery is full, it turns the charging off. That gives the upper limit for the calibration.

It doesn't really matter how fast you discharge the battery while you're doing the calibration, you can just use the device as normal. Of course with an e-reader this might take a few weeks or more!
That was what I was thinking of. For a laptop, you can put a movie on repeat, but the ereaders need interaction.

If you want to speed the process up then something that used WIFI and some processing would probably do the trick. I haven't played with the Kobo browser much, but if it supports Javascript then it should be pretty easy to make a web page that does something causes lots of processing and WIFI usage. Maybe some animation or a scrolling Twitter feed?
According to http://browserspy.dk/javascript.php, the browser supports Javascript 1.7, so this idea should be possible.
