Maybe not encryption, but integrity protection is very important for
laptops. GELI supports integrity protection for a while now. If you
don't protect integrity of your entire laptop disk, it is trivial to
trojan userland utilities and/or kernel and steal your password. If
someone needs your data, he can dump encrypted partition, trojan your
system and once you connect to the internet and attach your encrypted
partition, the trojan will send the password to the attacker. Many
people often leave their laptops in hotels rooms, for example.
