But should you in fact keep a laptop plugged in at all times?
This is, ultimately, an unanswerable question for a third party.
I generally keep mine plugged in at all times except when I need to "grab and go" and know I won't be using the laptop more than 2 to 3 hours off charger. I have never noticed much difference in battery life when I follow this practice than when I was religious about allowing the battery to drain to around 50% or lower and plugging in the charger only then.
It makes even less difference if your machine has lithium ion batteries (as anyone with a smartphone can tell you, the number of charge cycles on these is much higher than NiCd or NiMH batteries and they don't mind being constantly trickle charged). I actually do deep discharge and recharge cycles on the smartphones I've used far more than I ever have with a laptop (which gets used in place of a desktop for most of the time I'm using it. I stopped buying desktop units when laptops became every bit as reliable and stopped being priced at a ridiculous premium).
You have to read up on batteries and then make your choice depending on what you're trying to accomplish.

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
