My 17 " laptops are 7 and 6 years old and travel a lot (in fact this one is over 1,000 miles from home as I type...)
The ones before these were over 5 years when sold.
Keep them cool, stable and free of food and drink. (And out of the pool/shower/tub or sink)
Expect to go though some hard drives (as with desktops, but more frequently) - 1 every 3 to 5 years. This is normal and easily addressed.
P.S. - I love 6x9 three ring binders as they complement digest sized books.
