I am looking to buy a new laptop for business and personal use, and was planning to buy the MacBook Pro 2.0GHz. I visited my local Apple Store today to try it out, and was absolutely shocked at the poor performance of the machines on display. Specifically, animated text in PowerPoint was incredibly slow when rendering in the slideshow, in many cases causing the computer to "hang" for 30+ seconds. When typing in both PowerPoint and Word, text lagged by a second or two. Is this kind of performance normal for the MBP? I experienced the same performance level on 4, freshly restarted MBP display models, plus an Intel iMac, which was slightly better, but not by much. The Apple Store reps assured me that this issue was due to some kind of security software, and said that the software caches "everything users do" to ensure a clean system wipe at restart. They also said that this software doesnt appear in Activity Monitor. Activity monitor was showing PowerPoint using 607MB of virtual memory, and another process (that I don't remember and have never seen before) using 1.2GB of virtual memory. I would really like to buy the MacBook, as I have been an Apple user for some time, but PowerPoint is somewhat mission-critical for me. Thoughts/comments would be greatly appreciated. Thanks!
