what to do...

i have been thinking of upgrading the laptop memory instead of buying a new one. it's cheaper that way i think and the laptop i currently have is not really that old yet. oh, well. i don't really know what to do. i want to be reasonable and i don't want to just buy a laptop since the one i have is something that i could still use. what am i to do also with the laptop i have now if i do decide to but a new one. i can't sell it since it was given by my dad. sheesh!
