Star Update on the 12" Powerbook Review; Altitude Problems?
Linked by Eugenia Loli-Queru on Mon 3rd Mar 2003 20:39 UTC
Apple OSNews featured two reviews of the new 12" Powerbook from Apple last month. Using a machine and more fairly evaluating it, is a continuous process, so when new facts emerge, we should be reporting them back. So, what I discovered this weekend is that my 12" Powerbook doesn't like... the mountains. Read on, it is an interesting issue. Update: The issue is now logged at Apple's tech support db.

Swapping vs. virtual memory
by Chip Slush on Mon 3rd Mar 2003 23:19 UTC

Even if you have a huge amount of RAM, this does not necessarily mean virtual memory will not come into play. Most modern OS will leave unused parts of the program mapped, but not loaded. When the processor attempts to jump to a "virtually there" chunk, an exception occurs and the necessary block from the code file is paged in.

This leaves your 640MB of RAM open to debate by the system resource manager in case you decide to open photoshop while surfing with 97 instances of Safari opened ;)
