Not sure if this is the right place to post this but here goes... I have been thinking for a while about buying a Dell XPS M1530 as I need a Windows Laptop in addition to my MBP, and I have been emailed a 10% off coupon from Dell, which could save me £80 off the configuration I was looking at (2.4GHz C2D, 4GB Ram, 320GB Hard Drive, 1440 x 900). However, during the summer, I hope to be buying a Mac Pro to replace my Windows desktop, and wondering whether it's worth buying the Dell or not. What would the performance be like running Windows XP on my Macbook Pro? (It's a 2.16GHz Core 2 Duo with 2GB Ram, and 320GB Hard Drive). Would the performance be as good as a dedicated windows PC?
