like i said on the other laptop post, personally i wouldnt buy a dell.
less important components are budget and poor quality, and they feel cheap to me. (personal oppinion).
Also, another note: i wouldn't buy a macbook. apple charge incredibly high prices for hardware that just isnt worth that much, the best part of a macbook is the screen quality (in fairness, i was very impressed), but the rest i wouldnt say is worth it.
