New toy: a MacBook Pro to use as my new primary machine.
I put the other blog to good use—I decided to reinstall everything from scratch, rather than use a Time Machine restore (which would have transferred a bunch of cruft, and would have meant that all the binaries would be the slower PowerPC versions rather than Intel versions). A couple of days later, I'm done.
It's definitely faster than the old machine, but I don't have a good feel for by how much. I compared the time taken to rebuild one of my current projects (90 seconds vs. 255 seconds) but that was for quite a disk-bound build process, which will limit the advantage of the new machine.
