I just unpacked and installed the 1 GB RAM upgrade I ordered for the Macbook. Wow. Night and day. Everything seems just blindingly fast now, although I’m sure there’s a placebo effect at work. More importantly, WinXP running under Parallels Desktop is as smooth as butter, and running Snapz Pro X to record “video” of my WinXP desktop doesn’t diminish the speed any. So I expect screencasting will resume very soon.
