After waiting 9 months for the new MBP's to come out I went ahead and bought the 2.5ghz model with 2GB! I love this machine, well worth the wait and absolutely beautiful! I am currently saving up for the new cinema display to use with it! Anyway...my only concern is that even though this is almost the top range spec model I find that when I am using Quark and Photoshop at the same time, with Safari open as well, the response time is quite often, quite slow! Not what I would expect from such a superior machine! Can anyone pin point anything I could be doing wrong here? Also, I am looking to purchase 2GB memory to up my MBP to 4GB...which I believe will make my mac a little faster? Definately ready to buy and install so I am wondering what the cheapest and most reliable source to buy is in the UK? Thank you in advance!
