I have an Oct 08 alu 2.4 MB. I am considering upgrading to the 13" MBP 2.53, is there a massive difference or is it not worth it?
Ram, Video Card, Hard Drive Speed and what you are doing with it def. plays a factor...
...even with 4GB of RAM a VM isn't going to be "super fast" and your sig says you only have 2GB of RAM... the extra 2 GB of RAM in your machine would be the more cost effective thing to try before buying a new computer... but bootcamping into the other OS is still the most efficient use of your system resources...
My VMWare Boot Camp partition works just as well as the real thing for 99% of things I need it for.
It's probably more the fact that you can only give it one processing core (or a combination of the lack of RAM and processing cores, I could be wrong though), I'd wait until the new MBP range comes out before buying a MBP.I just find mine a little sluggish when I try to use Windows 7 in Parallels on it
