The majority of attacks discussed in the article you quote are when you 
generate (or use) your GPG key on untrusted hardware. As the original 
poster was discussing using their own laptop, then only applicable risk 
from that article is of someone shoulder surfing your passphrase.

Other risks, such as the use of tempest technologies to capture key 
presses or other internal details, do exist - but they assume an attacker 
with sufficient ability to be able to compromise your passphrase in 
numerous other ways.
