will this kill my battery?

Keeping li-ion batteries at a voltage of 4.2 is not recommended as it can cause premature corrosion. This is where the recommendation of not keeping them plugged in continually comes from. In some of the newer laptops, vie seen that the charge percentage drops to between 97 and 95% to keep it away from that 4.2v level.

Worse case, if you want to keep it plugged in, go for it. If you lose battery life, I'm sure there will be plenty of cheaper after market batteries available by the time you need a replacement. I also agree with the member that said draining them down all the way is not good as a practice because it isn't. I try to charge mine when it gets down to around 40%, but in the real world, this isn't always possible.
 
hmm, I'm used to my old phones that I had to completely cycle to make the batteries survive...I was anal about it and knock on wood have never had to buy a new battery for any of my phones before my 2 yr upgrade date. That said I'm seriously considering the extended battery for the inc. but it has me wondering if I should just start keeping an extra usb cord with me at work and keeping it charged while on my desk.
 
This is just a summary of what I've read over the years. I am not an expect on batteries or even a chemical engineer. This is just what I've read.

Lithium batteries should have a built in circuit to prevent overcharging. In general, Litihium batteries do not like to be deep cycled (and I've read that letting them go completely dead will actually kill the battery's life). However, the meter that reports your "percentage" will become inaccurate if you don't do a rather full discharge every now and then. (The evil fruit company recommends letting the battery go down to 20% or so and then charging fully about once every month to keep the meter accurate.)

Take this with a grain of salt.
