i'm looking for a laptop at the mo. in the last one year, i've had computer probs like fried motherboard, dead hard drive etc. so in my search for a laptop, my most important criteria is whichever brand offers the most efficient and best service in terms of repairs (i'm extremely reliant on my laptop and i don't have a desktop at my disposable.)

for example, do any of the laptop brands offer a replacement laptop while they fix your laptop? otherwise, which laptop brand has the best and most efficient service esp in terms of repairs. if location matters, i'll be primarily in wellington (in auckland on the odd occasion).
