spec my dad a Mac

[S.A.S]

my dad wants a new laptop and was looking into Macs and asked me for some help.

he doesn't want to spend more than 1500 pounds

he travels daily and was not sure if the little air book is tough enough to take the knocks and bumps off a train journey and walk through London in the rush hour.

he does archutechtural presentations on big screens, using all different pieces of software, that he has found works on mac, but they are GB HUNGRY

SO NOW HES THINKING OF THE MACBOOK OR MACBOOK PRo

couldanyone spec one please

i thought apple did not void the warranty if any third party RAM was installed that is Apple specific to that type of Mac?

i think he's going for the macbook 2.4ghx with 4gb of RAM, hes not one to take the back covers off things, so its probably the easiest option
