Had my 3 year old macbook stolen at uni so going to buy a MBP 15" laptop to replace it. I am in the midst of dissertation so time is the key. Are all these rumours about new MBP just rumours or will a new MBP be coming out within 'weeks'. Id rather travel to the library for a week or than fork out a grand on a MBP which is updated in a week. Thoughts ??
