How long will a Laptop survive?

i am not sure what does "good care" means
but i keep it by my bed and use it, otherwise I do not take out any where.
its connected to electricity 24/7

Avoid using it on the bed where the blanket will block the cooling fan and give it a source to suck in dust and get hot.

Macbook/Pro vents are basically around the LCD hinge, so would be hard to block with a blanket. At least entirely.

I thought the more you charge your battery and drain it, the faster the battery dies

I am not sure if macbook are bad, but my macbook seems to turn the fans so high for doing any kind of work other than simple browsing and viewing videos(if not flash)

photoshop(simple tasks), imovie, games, almost anything the fans will go crazy
and the worst is converting video files or ripping a DVD. Heat will be like 85-90C and fans are at 6000RPM

Depends on the battery and charger. If a charger is constantly trying to actually charge the battery, then it'll wear it out by keeping it plugged in. Since most modern gear is smarter than that, and will go to trickle charge, there shouldn't be an issue.

You won't save your battery by not using it on battery power either though. Might prevent it from getting conditioned badly, but it won't stay good as new.

That's pretty common for laptops in general. They normally run at a fraction of their rated speed, which is fine for simple tasks. When actually tasked with something strenuous, they throttle up, and produce more heat as a result. If it actually gets too hot, it'll throttle things down.

If you're doing a lot of CPU intensive tasks, you're better off with a desktop.
