Power charging: Only when depleted, or all the time?

Recently I replaced my battery and power plug for my MacbookPro, now 7 years old !  :)

Question.
Is it "wrong" to keep the power plugged in at all times?

If it is not the best thing to do, please explain why I should not keep the power running all the time.

Reason for the Question
1. By morning, the power has completely drained, and it takes a while for it to begin powering up again.
2. The power charge lasts only about 3 hours, and I have to plug in again.
So I am thinking I may as well stay plugged in at all times.

You're going to find conflicting reports if you try to do a google search.

Personally, whenever my laptop is on my desk, it is plugged into power.  This may or may not be the best thing to do, but I've never seen proof that this shortens the battery life.

If your battery is easily removable, you could try this:
1. remove battery
2. plug laptop into power supply
3. use laptop

Store the battery in a cool place with a partial charge. when you need the battery, insert it into the laptop and charge it.

I am not able to do this because my laptop has a non-removable battery.
And since a battery can only be charge x number of times, I just keep my laptop plugged in whenever it is on my desk.

I keep my MacBook Pro plugged in all the time.  It has a 'smart' charging circuit that lets the battery discharge a little before it starts charging it again so the old problem of 'battery memory' is not a problem.  That occurred with NiCads anyway and the MacBook Pro battery is a Lithium-Ion I believe.  Apple has a lot of info about their batteries: http://www.apple.com/batteries/
