On two fronts:
Keyboard: I’ve arranged for a RMA from OWC for the Tactile Pro, since the ghosting thing is too annoying. But then I found this page: http://www.macintouch.com/keyboards.html where a MacInTouch reader describes the exact same problem that I’m finding, and goes on the recommend that fast typists stay away from the Tactile Pro. If only I had seen that first. Anyhow, the same poster claims that he has contacted Matias, and they said that there will be a new version of the keyboard that fixes the problem, and that they’d do an exchange for the one he had already.
Interesting. So I just shot off an email to Matias about the issue to see what they can do about it. Maybe I got an older version?
Desktop/Laptop debate: I think I tried it out before, but it seems like Aperture runs reasonably well if I move the photo library to my external firewire drive, which is bigger and faster than the powerbook’s builtin drive. I can probably deal with this for now until I upgrade. 17 inch MacBook Pro looks mighty nice.
BTW, I wonder if a Powerbook G4 can take 4GB of RAM (with the new 2GB SO-DIMM’s that are just starting to come out)?
