I hope they will release new MacBook Pros with the core i7 mobile CPUs this month.... I'd like to jump in the MBPro world, but not with the current technology, which I already have on my Santech X3620 laptop... Buying a MBP 17" is a big investment (with the same amount of money you can buy a Santech laptop with the latest technology, from the CPU, to the HDDs ecc), but I feel it's the time to try to jump into the "mac world".. It would be the time also to upgrade the GPUs of the MBPros, since they are quite old, but it is not a priority for me.. With technologies like GCD, a 4-core CPU with HyperThreading (8 logical CPUs) will be a very good thing, as soon as developers starts using it in their programs... so, let's wait and hope for an upgrade, even if we are only in the middle of the usual production cycle
