Dmitry, which notebook are you considering? usually you can look up the particular notebook somewhere like
http://www.memorystock.com/dell-memory.htm and contact them directly about concerns re compatibility etc. You may be shocked at the price difference. ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
