Last week, I ordered a new Unibody 15" Macbook Pro (2.53ghz/4gb/250gb@7200) and the wait for it is agonising! With UPS customs issues and holiday delays (I didn't realise that China shuts for almost a week at their New Year!) There's a bit of a worry in my mind that it might not make it's delivery date of Monday the second, but it'll get here eventually! At the moment I'm using a 15" MacbookPro1,1 (2.0ghz/2gb/100gb@7200) and I get the feeling it knows it's being replaced as it's started doing some funny things to me (such as bluetooth disappearing, airport connection playing up, boot delays, etc), but what I would like to know is what sort of difference will I see with this new machine speed/power wise? Is it going to be a world of difference in day to day stuff, or just a bump? I can't wait to see this machine, I'm really excited about it!
